I'm using PI Performance Monitoring Interface and I found out this beahaviour with the Queued Events Rate

It seems like every 10 minutes or so this indicator presents high values, I want to know:

1. If this represents a performance issue.

2. If I can identify the root cause for this behaviour.


Also, the Compression Rate lowers drastically during the same time.


On a different time, I found out that the snapshots rate presents really high values, and I wanted to identify the cause for this.


I'd appreciate any help on this topic.

Kind regards.



PS: already went trough the procedure in this kb: https://customers.osisoft.com/s/knowledgearticle?knowledgeArticleUrl=3223OSI8  (How to find and disconnect a rogue consumer or heavy hitter) but I couldn't really identify a cause.
