Hello,
We are integrating our on-prem Splunk (version 8.2.3) to retrieve messages from an Azure Event Hub. We have configured Linux server syslog to send to an Event Hub (Linux diagnostic extension 4.0).
We installed the Splunk Add-on for Microsoft Cloud Services app (version 4.2.0), configured the Azure app account, and created the inputs to map to the Event Hub namespace/hub name/consumer group.
We are seeing data arrive into Splunk, but it is arriving split across multiple events:
If I add all three events together, it is valid JSON for a single event:
{"body":{ "time" : "2021-11-30T23:30:01.0000000Z",
"resourceId" : "/subscriptions/xxx/resourceGroups/xxx/providers/Microsoft.Compute/virtualMachines/xxx",
"properties" : {
"ident" : "CRON",
"pid" : "177365",
"Ignore" : "syslog",
"Facility" : "authpriv",
"Severity" : "info",
"EventTime" : "2021-11-30T23:30:01+0000",
"SendingHost" : "localhost",
"Msg" : "pam_unix(cron:session): session closed for user root",
"hostname" : "xxx",
"FluentdIngestTimestamp" : "2021-11-30T23:30:01Z"
},
"category" : "authpriv",
"level" : "info",
"operationName" : "LinuxSyslogEvent"
},"x-opt-sequence-number":100,"x-opt-offset":"77128","x-opt-enqueued-time":1638315007941}
But we need such to be a single event in Splunk in order to process data effectively!
Interestingly enough, we are using the Event Hub integration to also retrieve resource diagnostic logs, and we don't see the same issue! Only when using Event Hubs for Linux diagnostics.
Has anyone faced this issue, or know how to correct the problem? Thanks!
