Data Collector Polling Status Data Catching Up

CA Performance Management - Usage and Administration DX NetOps


We have DX NetOps 20.2.5, Data Aggregator with two data collectors. 

Everything seems to appear normal, but both data collectors show a Polling Status of "Data Catching Up". 

I'm trying to determine the significance of that, please advise


Dx NetOps Performance Management 20.2.x



The DC status 'Data Catching Up' is new with 20.2.x.  

It means there is pending data on the DC.  

You may see that status for a period of time after a DA restart.  

You could also see if with a prolonged network disconnect between DC and DA, or if there are memory issues on the DA as well.

Additional Information

Also if you are working in DA Fault Tolerance and see all DC's with Inactive/Not Collection and Data Catching up Status check:

df -h, df -i and ll commands doesn't respond

cd for DA Proxy FS shared (/opt/DASharedRepo/data) doesn't works also

On NFS Server machine run:
showmount -e
clnt_create: RPC: Unable to send
systemctl restart nfs
now showmount -e works fine

Restart dcmd and activemq Services in all  DC's
