I want to use SSO and reverse proxy to skip the login page and go directly to the service app page. I found several resources and created a setup as shown below, but it doesn't skip the login when accessing those addresses. The environment is as follows Ubuntu 20.04.6 Nginx 1.18 Splunk 8.2.9 Is it possible to implement login skipping with this configuration alone? Or is this possible with additional authentication services such as ldap or IIS authentication, SAML, etc? If so, what additional areas of the above setup should we be looking at?    web.conf   [settings] SSOMode = strict trustedIP = 127.0.0.1,192.168.1.142,192.168.1.10 remoteUser = REMOTEUSER tools.proxy.on = true root_endpoint = / enableWebDebug=true     server.conf   [general] serverName = dev-server sessionTimeout = 24h trustedIP = 127.0.0.1 [settings] remoteUser = REMOTEUSER   nginx.conf   server { listen 8001; server_name splunkweb; location / { proxy_pass http://192.168.1.10:8000/; proxy_redirect / http://192.168.1.10:8000/; proxy_set_header REMOTEUSER admin; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header X-Forwarded-Proto $scheme; } }

I have a search that captures a specific product code, calculates the total number of units attributed to the product code that were sold over the timeframe assigned to the search (say, seven days), and presents the data as a timechart. The search also references a lookup table to provide a "human friendly" name that matches the product code, along with a baseline value which reflects a specific number of units expected to be sold each day. The search looks like this... sourcetype=foo index=bar item="productA" | lookup product_table.csv productCode AS item | timechart span=1d sum(product_count) as volume by item | eval baseline = max(dailyBaseline)   ...and the lookup table looks like this: productCode name dailyBaseline productA Widget 5000 productB Thingamajig 10000   I would like the ensuing chart to show the baseline I've defined in the lookup table. If I replace "max(dailyBaseline)" in the eval statement with a static value such as 5000, it works fine. I can't figure out how to get the "dailyBaseline" value from the lookup table to work, though.

I am working on ingesting the WSJT-X log. I got to where I have the basic fields in Splunk and wanted to create a date and time stamp from the poorly formatted data.  I started with a very basic eval statement to test this and I am not seeing the new field.

If you find issue happens after windows server is restarted. Restarting splunk universal forwarder fixes the issue. Then try one of the following workarounds. Use 'Delayed Start' for the Splunk Forwarder service. ( https://community.splunk.com/t5/Getting-Data-In/Why-quot-FormatMessage-error-quot-appears-in-indexed...). However it's hard to configure thousands of DCs. Or Configure  interval as cron schedule instead. interval = [<decimal>|<cron schedule>]   [WinEventLog] interval=* * * * *   By default wineventlog interval is 60 sec. That means as soon as splunk is restarted, wineventlog (or any modinput) is immediately started. Subsequently every 60( configured interval) splunk checks if modinput is still running. If not re-launch modinput. Instead of setting interval 60 sec, if we use cron schedule to run every minute, then splunk is not going to launch modinput immediately. So essentially the idea is to convert interval setting from decimal to cron schedule to introduce a delay. If above does not solve the issue, meaning the issue is not related to windows server  restart.  Try one of the following workarounds.   Workaround 1. in inputs.conf Stop UF Set batch_size to 1. Start UF [<impacted channel>] batch_size=1 Workaround 2. in inputs.conf Stop UF backup checkpoint file $SPLUNK_HOME\var\lib\splunk\modinputs\WinEventLog\<impacted channel> . Saves current record id  In inputs.conf for impacted channel add use_old_eventlog_api=true Start UF Stop  UF after 30 sec Replace current record with  record id found in step 2. So that ingestion starts from right place. When setting use_old_eventlog_api=false ( in case if it does help). Follow all above steps so that UF correctly starts from desired record id.  [<impacted channel>] use_old_eventlog_api=true

I finetuned LLM and I want to integrate that with Splunk. In Splunk Dashboard, I am going to include Question/Answering mechanism where my model going to answer the question user has.  For that, I have created an app "customApp" in src/etc/apps and added user-queries.py file in apps/customApp/bin folder and command.conf file in apps/myapp/default folder.  I loaded the finetuned model and generated response in user-queries.py  I am getting the following error on Splunk dashboard when calling this command. Btw, it worked when I hardcoded instead of loading the model and asking model to generate responses. <Error in 'userquery' command: External search command exited unexpectedly with non-zero error code 1.> Am I following the correct approach to integrate LLM to Splunk? I checked my splunkd.logs, it shows some disk space issue. Can you someone please save me from this, Thanks in advance!

We pull weekly vulnerability reports from Splunk associated with our Qualys data.  I am trying to filter out all records associated with a hostname if the status field equals "Fixed". The data for a couple hosts might look like this:   Date Host Status 2024-07-22 host1 NEW 2024-07-22 host2 NEW 2024-07-23 host1 ACTIVE 2024-07-23 host2 ACTIVE 2024-07-24 host1 ACTIVE 2024-07-24 host2 ACTIVE 2024-07-25 host1 FIXED 2024-07-25 host2 ACTIVE 2024-07-26 host2 ACTIVE 2024-07-27 host2 ACTIVE 2024-07-28 host2 ACTIVE 2024-07-29 host2 ACTIVE   Both host1 and host2 discover a new vulnerability on 7-22.  On 7-23, the status for both flip to "ACTIVE".  On 7-25, however, host1 is now showing a FIXED status. Host2 remains vulnerable through the remaining date range of the report. Since host1 fixed the vulnerability during the timeframe, how could I go about removing all host1 events based on the status field being equal to "Fixed" on the most recent data pull?

We are in the midst of migrating our Splunk from Ubuntu to RHEL 9 Stigged. Supposedly, this should have been copy paste, minor clean up, start Splunk. it has been anything but that. Error after error and problem after problem. I finally have it narrowed down to a certificate error; an error that doesn't really make sense since everything worked fine on the other server. The server name and IP address are the same as the old server. They weren't set that way initially since I was using rsync to move things but after a couple errors, I realized I needed to fix that. I set the IP and hostname to the same as the old one, powered off the old server, and rebooted the new one to make sure settings were correct.  Currently, I'm seeing a bunch of python errors in splunkd.log.    Error ExecProcessor -message from "<splunkhome>/bin/python3.7 /<splunkhome>/etc/apps/search/bin/quarantine_files.py" from splunk.quarantine_files.configs import get_all_configs.   This error reports dozens of times but changes the file from. Eventually it ends with   ERROR ExecProcessor [33034 ExecProcessor] - message from "/<splunkhome>/bin/python3.7 /<splunkhome>/etc/apps/search/bin/quarantine_files.py" MemoryError IndexProcessor [32848 MainThread] - handleSignal : Disabling streaming searches. IndexProcessor [32848 MainThread] - request state change from=RUN to=SHUTDOWN_SIGNALED ProcessRunner [32850 ProcessRunner] - Unexpected EOF from process runner child! ProcessRunner [32850 ProcessRunner] -helper process seems to have died (child killed by signal 15: Terminated) !     In mongod.log I get "error receiving request from client: SSLHandshakeFailed: SSL peer certificate validation failed: unsupported certificate purpose. Ending connection from <server IP>". When running splunk start, it says waiting for web server..... and eventually fails saying web interface does not seem to be available. I'm unclear if this or the python errors causes Splunk to stop but within about 10 minutes of starting Splunk, it stops. Previous to this, it was giving me an error about the kvstore (I don't remember it). After some digging, I discovered that I also had to add a section to the server.conf for kvstore to use a certificate. That's apparently a requirement when running FIPS... Except another RHEL system runs it fine without the certificate... The next error was about the hostname not matching the cert. The hostname it listed was 127.0.0.1 which is not what the hostname is set to. I manually set it to the server IP with SPLUNK_BINDIP in splunk-launch.conf and that cleared that issue but it still doesn't load the web page and I now get the certificate error. It feels like it's connecting to itself as a client for some reason and failing the certificate. Did I configure something wrong? We've never had to set that manually so I found it odd that we to when moving to RHEL. I found another post that indicated I could check if the certificate was a server and client with the -purpose. Unfortunately (and unsurprisingly) it's server only. I have been trying to figure out either A) how to get it to stop asking for the client certificate or B) how to create a certificate that acts as both server and client... or I guess C) how to create the client certificate and where to place it. All of our certs are probably server only. We have our own CA so we aren't doing self-signed. Any thoughts? Any tips on any of these issues would be appreciated.

I am trying to ingest some json data into a new Splunk Cloud instance, with a custom sourcetype, but I keep getting duplicate data in the search results. This seems to be an extremely common problem, based on the number of old posts, but none of them seem to address the Cloud version. I have a JSON file that looks like this: { "RowNumber": 1, "ApplicationName": "177525278", "ClientProcessID": 114889, "DatabaseName": "1539703986", "StartTime": "2024-07-30 12:15:13" }   I have a Windows 2022 server with a 9.2.2 universal forwarder installed. I manually added a very simple app to the C:\Program Files\SplunkUniversalForwarder\etc\apps folder. inputs.conf contains this monitor [batch://C:\splunk_test_files\ErrorMaster\*.json] move_policy=sinkhole index=centraladmin_errormaster sourcetype=errormaster props.conf contains this type  (copied from _json) [errormaster] pulldown_type = true INDEXED_EXTRACTIONS = json KV_MODE = none category = Structured description = JavaScript Object Notation format. For more information, visit http://json.org/ On the cloud side I created (from the UI) a new sourcetype called 'errormaster' as just a direct clone of the existing _json type. When I add a .json file to the folder, it is ingested and the events show up in the cloud instance, under the right correct centraladmin_errormaster index, and with the sourcetype=errormaster. However, the fields all have duplicate values.   If it switch it to the built-in _json type it works fine. I have some field extractions I want to add, which is why I wanted a custom type. I'm guessing this is something obvious to the Cloud experts, but I am an accidental Splunk Admin with very little experience, so any help you can offer would be appreciated.

Hello community. We have a cluster architecture with 5 indexes. We have detected high license consumption, we are trying to identify the sources that generate it. I am using the following search to find out which Windows index host consumes the most license: index=_internal type="Usage" idx=wineventlog | eval MB=round(b/1024/1024, 2) | stats sum(MB) as "Consumo de Licencia (MB)" by h | rename h as "Host" | sort -"Consumo de Licencia (MB)" With this search I can see the hosts and the consumption in megabytes, but in the h field, there are no values ​​or hosts, which I cannot identify and I need to know which are those hosts, since the sum of all of them gives me a high license consumption. What could be the cause of that?     this is the events from uknowns_host: I cannot identify what they are, if they are a specific host, if it is a Splunk component, or something that is causing this license increase.

https://github.com/Cisco-Observability-TME/ansible-smartagent-install   Introduction Welcome, intrepid tech explorer, to the ultimate guide on deploying the Cisco AppDynamics Smart Agent across multiple hosts! In this adventure, we'll blend the magic of automation with the precision of Ansible, ensuring your monitoring infrastructure is both robust and elegant. So, buckle up, fire up your terminal, and let's dive into a journey that will turn your deployment woes into a seamless orchestration symphony. Steps to Deploy Cisco AppDynamics Smart Agent Step 1: Install Ansible on macOS Before we embark on this deployment journey, we need our trusty automation tool, Ansible. Follow these steps to install Ansible on your macOS system using Homebrew: Install Homebrew (if not already installed): /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)" Install Ansible: brew install ansible Verify the Installation: ansible --version You should see output indicating the installed version of Ansible. Step 2: Prepare Your Files and Directory Structure The project directory should contain the following files: ├── appdsmartagent_64_linux_24.6.0.2143.deb ├── appdsmartagent_64_linux_24.6.0.2143.rpm ├── inventory-cloud.yaml ├── inventory-local.yaml ├── inventory-multiple.yaml ├── smartagent.yaml └── variables.yaml Step 3: Understanding the Files 1. inventory-cloud.yaml, inventory-local.yaml, inventory-multiple.yaml These inventory files list the hosts where the Smart Agent will be deployed. Each file is structured similarly: all: hosts: smartagent-hosts: ansible_host: <IP_ADDRESS> ansible_username: <USERNAME> ansible_password: <PASSWORD> ansible_become: yes ansible_become_method: sudo ansible_become_password: <BECOME_PASSWORD> ansible_ssh_common_args: '-o StrictHostKeyChecking=no' Update these placeholders with your actual host details. Explanation of smartagent.yaml This Ansible playbook is designed to deploy the Cisco AppDynamics Smart Agent on multiple hosts. Let's break down each section and task in detail. Playbook Header --- name: Deploy Cisco AppDynamics SmartAgent hosts: all become: yes vars_files: - variables.yaml # Include the variable file name: Describes the playbook. hosts: Specifies that the playbook should run on all hosts defined in the inventory. become: Indicates that the tasks should be run with elevated privileges (sudo). vars_files: Includes external variables from the variables.yaml file. Tasks Ensure required packages are installed (RedHat) - name: Ensure required packages are installed (RedHat) yum: name: - yum-utils state: present update_cache: yes when: ansible_os_family == "RedHat" Uses the yum module to install the yum-utils package on RedHat-based systems. The task runs only if the operating system family is RedHat (when: ansible_os_family == "RedHat"). Ensure required packages are installed (Debian) - name: Ensure required packages are installed (Debian) apt: name: - curl - debian-archive-keyring - apt-transport-https - software-properties-common state: present update_cache: yes when: ansible_os_family == "Debian" Uses the apt module to install necessary packages on Debian-based systems. This task is conditional based on the operating system family being Debian. Ensure the directory exists - name: Ensure the directory exists file: path: /opt/appdynamics/appdsmartagent state: directory mode: '0755' Uses the file module to create the directory /opt/appdynamics/appdsmartagent with the specified permissions. Check if config.ini exists - name: Check if config.ini exists stat: path: /opt/appdynamics/appdsmartagent/config.ini register: stat_config Uses the stat module to check for the existence of config.ini and registers the result in stat_config.

The content field uses Jinja2 templating to populate the configuration with variables from variables.yaml. Configure Smart Agent - name: Configure Smart Agent lineinfile: path: /opt/appdynamics/appdsmartagent/config.ini regexp: '^{{ item.key }}=' line: "{{ item.key }}={{ item.value }}" loop: - { key: 'AccountAccessKey', value: "{{ smart_agent.account_access_key }}" } - { key: 'ControllerURL', value: "{{ smart_agent.controller_url }}" } - { key: 'AccountName', value: "{{ smart_agent.account_name }}" } - { key: 'FMServicePort', value: "{{ smart_agent.fm_service_port }}" } - { key: 'EnableSSL', value: "{{ smart_agent.ssl | ternary('true', 'false') }}" } Uses the lineinfile module to ensure specific lines in config.ini are present and correctly configured. Set the Smart Agent package path (Debian) - name: Set the Smart Agent package path (Debian) set_fact: smart_agent_package: "{{ playbook_dir }}/appdsmartagent_64_linux_24.6.0.2143.deb" when: ansible_os_family == "Debian" Uses the set_fact module to define the path to the Smart Agent package for Debian systems. Set the Smart Agent package path (RedHat) - name: Set the Smart Agent package path (RedHat) set_fact: smart_agent_package: "{{ playbook_dir }}/appdsmartagent_64_linux_24.6.0.2143.rpm" when: ansible_os_family == "RedHat" Defines the path to the Smart Agent package for RedHat systems. Fail if Smart Agent package not found (Debian) - name: Fail if Smart Agent package not found (Debian) fail: msg: "Smart Agent package not found for Debian." when: ansible_os_family == "Debian" and not (smart_agent_package is defined and smart_agent_package is file) Uses the fail module to halt execution if the Smart Agent package is not found for Debian systems. Fail if Smart Agent package not found (RedHat) - name: Fail if Smart Agent package not found (RedHat) fail: msg: "Smart Agent package not found for RedHat." when: ansible_os_family == "RedHat" and not (smart_agent_package is defined and smart_agent_package is file) Halts execution if the Smart Agent package is not found for RedHat systems. Copy Smart Agent package to target (Debian) - name: Copy Smart Agent package to target (Debian) copy: src: "{{ smart_agent_package }}" dest: "/tmp/{{ smart_agent_package | basename }}" when: ansible_os_family == "Debian" Uses the copy module to transfer the Smart Agent package to the target host for Debian systems. Install Smart Agent package (Debian) - name: Install Smart Agent package (Debian) command: dpkg -i /tmp/{{ smart_agent_package | basename }} when: ansible_os_family == "Debian" Uses the command module to install the Smart Agent package on Debian systems.

Install Smart Agent package (RedHat) - name: Install Smart Agent package (RedHat) yum: name: "/tmp/{{ smart_agent_package | basename }}" state: present disable_gpg_check: yes when: ansible_os_family == "RedHat" Uses the yum module to install the Smart Agent package on RedHat systems. Restart Smart Agent service - name: Restart Smart Agent service service: name: smartagent state: restarted Uses the service module to restart the Smart Agent service to apply the new configuration. Clean up temporary files - name: Clean up temporary files file: path: "/tmp/{{ smart_agent_package | basename }}" state: absent Uses the file module to remove the temporary Smart Agent package files from the target hosts. 3. variables.yaml This file contains the variables used in the playbook: smart_agent: controller_url: 'tme.saas.appdynamics.com' account_name: 'ACCOUNT NAME' account_access_key: 'ACCESS KEY' fm_service_port: '443' ssl: true smart_agent_package_debian: 'appdsmartagent_64_linux_24.6.0.2143.deb' smart_agent_package_redhat: 'appdsmartagent_64_linux_24.6.0.2143.rpm' Explaining the Variables File In Ansible, variables are used to store values that can be reused throughout your playbooks, roles, and tasks. They help make your playbooks more flexible and easier to maintain by allowing you to define values in one place and reference them wherever needed. Variables can be defined in several places, including: Playbooks: Directly within the playbook file. Inventory files: Associated with hosts or groups of hosts. Variable files: Separate YAML files that are included in playbooks. Roles: Within the defaults and vars directories of a role. Command line: Passed as extra variables when running the playbook. Variables can be referenced using the Jinja2 templating syntax, which is denoted by double curly braces {{ }}. The provided variables file is a YAML file that contains a set of variables used in an Ansible playbook. Here is a breakdown of the variables defined in the file: smart_agent: controller_url: 'tme.saas.appdynamics.com' account_name: 'ACCOUNT NAME' account_access_key: 'ACCESS CODE HERE' fm_service_port: '443' ssl: true smart_agent_package_debian: 'appdsmartagent_64_linux_24.6.0.2143.deb' smart_agent_package_redhat: 'appdsmartagent_64_linux_24.6.0.2143.rpm' smart_agent: This is a dictionary (or hash) containing several key-value pairs related to the configuration of a "smart agent". controller_url: The URL of the controller. account_name: The name of the account. account_access_key: The access key for the account. fm_service_port: The port number for the service. ssl: A boolean indicating whether SSL is used. smart_agent_package_debian: The filename of the Debian package for the smart agent. smart_agent_package_redhat: The filename of the Red Hat package for the smart agent. Step 4: Execute the Playbook To deploy the Smart Agent, run the following command from your project directory: ansible-playbook -i inventory-cloud.yaml smartagent.yaml Replace inventory-cloud.yaml with the appropriate inventory file for your setup. And there you have it! With these steps, you're now equipped to deploy the Cisco AppDynamics Smart Agent to multiple hosts with ease. Happy deploying!
