1. Describe your incident:
I’m “new” to graylog (been trying to get it to work for a month). I can send messages from my unifi server to my graylog with (echo “message” | ncat - u xxx.xx.xx.xxx port) but nothing else is coming through. I’m getting a warning/error in log/opensearch/graylog.log =
[2024-04-09T09:59:41,067] [WARN] [o.o.p.c.u.JsonConverter] [xxxxx] Json Mapping Error: Cannot invoke "java.lang.Long.longValue()" because "this.cacheMaxSize" is null (through reference chain: org.opensearch.performanceanalyzer.collectors.CacheConfigMetricsCollector$CacheMaxSizeStatus["Cache_MaxSize"])
2. Describe your environment:
I’m using proxmox VM. 8gb ram and 64gb (Test vm to see if we actually wanna use graylog)
- OS Information: Ubuntu 22.04 liverserver
3. What steps have you already taken to try and solve the problem?
I’ve scoured the internet for a solution and i cant seem to find anything related to this problem. I’ve checked that files av the premissions they need. Checked preformance analyzer.properties for a solution there.
If anyone can help i’d much appreciate it!
Disclaimer: I’m new to working with servers so there might be solutions i’ve missed
