This is an old topic but I have been able to fix this many times in different environments: What you need to do on the forwarder host is rebuild the counters:   To repair this you take the following steps to repair/rebuild the performance counters.

Hi, The reduction of this can have many different reasons, but you need to pinpoint what exactly changed. - Are all hosts patched and are all reporting and running the UF properly? - Can you pinpoint the reduction to System / Application or Security windows events? (source in splunk) - Do all hosts have the same amount of reduction of event logs sent to splunk? - Look at the windows eventcodes; Do a before and after count of the different eventcodes. Can you pinpoint a difference to a specific eventcode? Just troubleshoot step by step. Happy to help and think with you for next steps. ... View more

Hi, There is no app on splunkbase for Imperva DAM according to me. At least when I search for it I was not able to find it. You can't use the WAF Add-On because that is for a different product. It will not work I assume when reading the documentation. You are telling me that you receive the logs in CEF format in Splunk already? Why not create your own app to parse the fields to your needs? ... View more

Hi, Did you read the following?: https://docs.splunk.com/Documentation/SplunkCloud/8.2.2203/RESTTUT/RESTandCloud Accessing the Splunk Cloud Platform REST API You might need to take extra steps to access your Splunk Cloud Platform deployment using the Splunk REST API and SDKs. If necessary, you can get access with one of the following options: Use the Admin Config Service (ACS) API search-api/ipallowlists endpoint to add IP addresses to the search-api allow list. For more information about the search-api/ipallowlists endpoint, see Configure IP allow lists for Splunk Cloud Platform. Submit a support case requesting access using the Splunk Support Portal. Splunk Support opens port 8089 for REST access. You can specify a range of IP addresses to control who can access the REST API, so make sure your request includes the IP addresses or CIDR ranges that you want access from. Free trial Splunk Cloud Platform accounts cannot access the REST API. Once you have REST API access, you can make calls with a local account, an LDAP account, or a SAML account. To learn more about setting up authentication with tokens, see Set up authentication with tokens. Use the following URL for Splunk Cloud Platform deployments: https://<deployment-name>.splunkcloud.com:8089   ... View more

I believe this is because the tstats command performs statistical queries on indexed fields in tsidx files. Some time ago the Windows TA was changed in version 5.0.1 of the Windows TA. See: Sourcetype changes for WinEventLog data  This means all old sourcetypes that used to exist (and where indexed!) where named for example WinEventLog:System or WinEventLog:Application or WinEventLog:Security. They all have been renamed to WinEventLog by the newer version of Windows TA. But since they where indexed in the past they still exists in the metadata. And since tstats only looks at the indexed metadata you see these old sourcetypes appear. ... View more

That is correct. An admin is able to run these macro's or they need to give you access to run them and or access to the notable index too. Then you can run:   `suppressed_notables` | stats c by rule_name   This will give you a count of the amount of suppressions per rule name / colleration search. ... View more
