Hi Walter, There are a number of metrics available for every process, and depending on how you've configured the "Monitoring Mode", you'll see more as you enable "KPI", "Advanced", or "Diagnostic" detail.  If you enable "Advanced" via configuration or interactively via the UI, you will see the process "Count" metric collected. e.g. Application Infrastructure Performance|Root|Individual Nodes|cvpcclab|Hardware Resources|Process|tomcat9|Count Your Health Rule should trigger when Count < 1, and "Evaluate true on no data" if you want to be alerted when the agent stops reporting to the Controller for any reason. You will specify a Custom Metric Path for the metric, e.g. Hardware Resources|Process|tomcat9|Count ... View more

Since the API does not provide a "filter by Health Rule Name" option, your best bet is to fetch all the Health Rule violations, then iterate through them and ignore the ones not associated with the target Health Rule. Regards, ... View more

The AppDynamics Controller manages a pool of licenses. When a new JVM is started with the -javaagent and -D agent terms, the agent will connect to the Controller and request a license. If a license is available, the JVM will come up instrumented and continue to report to the Controller until the JVM is shut down. The license will be released back into the pool within five minutes of the JVM shutdown. If a license is not available, the JVM will startup instrumented, but the agent will not collect or publish any data, but will continue to ping the Controller every minute to determine if a license is available. If a license becomes available, the agent will turn itself back on and start reporting metrics to the Controller. License Management Scope configuration allows you to assign licenses to specific applications and machines. Using scopes to configure licenses allows you to express and scale the configuration modules as required. https://docs.appdynamics.com/display/PRO45/License+Management has details.  Another customer set up a Web Service that's called from the app server startup script with App Name, Tier Name, Node Name. The Web Service determines if the target JVM should be instrumented based on a local lookup, If the JVM should be instrumented, the Web Service will return the agent terms, -javaagent and -D's, and the JVM will start up instrumented. If the JVM doesn't match the criteria for instrumentation, the Web Service returns nothing and the JVM starts up without instrumentation. Hope these two possible approaches help you, ... View more

According to https://docs.appdynamics.com/display/PRO45/Hardware+Resources+Metrics: Avg IO Utilization (%): The average time spent processing read/write requests on all disks and partitions as a percentage of the total reported time window. Databases often report high disk I/O utilization due to frequent read/write requests. For example, if the agent detects read/write processing in 55 out of 60 seconds, the Avg IO Utilization for that minute is 92%. This metric does not measure the amount of available disk space or read/write request sizes. Regards, ... View more

Hi Hala, AppDynamics does not use or generate Lua script files. Does "ISO8583 sessions" relate to browser sessions initiated by Point Of Sale systems? If so, what distinguishes a "ISO8583 session" from an non-POS session, and how would this be used in a Snort engine or firewall engine? Just trying to understand the use case. Regards, ... View more

From the error message, it looks like the UI failed to launch due to a missing Font resource. To work around the problem, I would recommend completing the installation with the "silent" option by providing the inputs in a file: ./platform-setup-64bit-linux.sh -q -varfile ~/response.varfile -dir ~/appdynamics/platform Sample response file for silent installation:  Linux serverHostName=HOST_NAME sys.languageId=en disableEULA=true platformAdmin.port=9191 platformAdmin.databasePort=3377 platformAdmin.databasePassword= ENTER_PASSWORD platformAdmin.databaseRootPassword= ENTER_PASSWORD platformAdmin.adminPassword= ENTER_PASSWORD platformAdmin.platformDir=/opt/appdynamics/platform  Regards, ...

According to the documented Platform Requirements, the following Linux systems are tested and supported:  RHEL 6.x and 7.x CentOS 6 and 7 Ubuntu 14 and 16 SUSE 12 Similar Linux variants are likely to work but are untested, so we recommend deploying the AppDynamics Platform to one of these.

Minute-level data is available for time ranges within the last four hours as described at https://docs.appdynamics.com/display/PRO45/Metric+Data+Resolution+over+Time Older time ranges will be rolled up to 10 minute or one-hour summaries with Min, Max, Average, and Sum. Both of your screenshots show the one-minute data. Regards, ... View more

You can see JVM and Garbage Collection metrics in a couple of places: 1. Go to "Tiers and Nodes" in the left panel and select "Memory (Java)" from the dropdown menu at the top. Columns show key Heap and GC metrics across all Tiers, Nodes on the page. 2. From "Tiers and Nodes", drill down on any Java node and select the "Memory" tab at the top. See screenshot attached. ...

Hi Wahyu, The APM Any Language Agent works by allowing you to monitor one unit of any language concurrently. It works with OR, not AND. If you have a Java application with one JVM plus a .NET application running on one host, you need two "APM Any" licenses to monitor both applications at the same time. AppDynamics licenses work a bit like a library where one license allows you to check out any book at any time. As long as you have that book (agent is reporting to the Controller), that license is in use and you can't take out any other books (instrument any other apps with that license). When you shut down the instrumented app server, that license is returned to the pool within five minutes (and you can check out another book).   Second Illustration: Q: If the customer decide to stop monitor a certain site (the old version of customer website; build on .Net) and decide to move to another site (the new version of customer website; build on Java)? Do we need to revoke the previous agent license before we use it to the new agent license? A: Yes. You would stop the .NET application and restart it uninstrumented. That will free up the license(s) so that they can be used to instrument the new (Java-based) application. Regards, ... View more
