Reports Manager Pause Duration Issue

Contributor

Hello All,

Off late we have been getting concerning alerts for Reports Manager (The health test result for REPORTS_MANAGER_PAUSE_DURATION has become concerning: Average time spent paused was 35.6 second(s) (59.41%) per minute over the previous 5 minute(s). Warning threshold: 30.00%.) occasionally reports manager service also goes to bad state.

I believe, this has to do with Reports Manager Heap Memory, but am in a doubt hence wanted to get a confirmation before playing around with it. I have attached a snippet of the error, which I get.

Also would like to know if there is any reference guide / document by which, we can calculate and periodically adjust such items.

HDFS Used – 10TB / Total 90TB
FSImage – 980M
CM - 6.16.2 / CDH - 5.16.2

The health test result for REPORTS_MANAGER_PAUSE_DURATION has become concerning: Average time spent paused was 35.6 second(s) (59.41%) per minute over the previous 5 minute(s). Warning threshold: 30.00%.

So based on 1GB fsimage file, you need to have at least 4GB+ for RM to function properly. Please try to increase and observe if there is improvement.

Hi @wert_1311 ,

 

It has been a long time since I looked at sizing, so I forget the specifics.  The following rule has helped in the past, though:

 

(4 x fsimage_size) + 3GB

 

So, if your fsimage is 980, 7 or 8GB should be appropriate as a starting point.

 

The Reports Manager downloads the fsimage from the NameNode and then parses/indexes it, so this it needs enough heap to fit the fsimage in memory plus overhead for the indexing process.

 

Based on what you have collected, increasing the Reports Manager heap sounds like the right call.

Just make sure you have enough free memory on the host before increasing the heap.

@wert_1311,

Yes, @bgooley is right, it is 3-4 times of fsimage, documentation here:
https://docs.cloudera.com/documentation/enterprise/release-notes/topics/hardware_requirements_guide....

What's the current heap setting for RM?

Cheers
Eric
