I was getting the following alerts regarding the custom poller on NNMi which was annoying users with the constant on/off status alerts.
“The Performance SPI Custom Poller Bus Adapter has status Critical because the average input queue duration…..”
“The CustomPoller Export Bus Adapter has status Minor because file space limit (2,000 MB) has been reached and older export data files are being removed to make room for new files.”
After some digging, it seems that the older files weren’t being deleted so this issue had actually crept up over time.
Apparently this was fixed by patch 5 but a workaround until then is to delete older files manually as follows. I strongly suggest running the find command without the “| xargs rm” part first to verify that you are indeed only finding regular files within the correct directory.
# cd /var/opt/OV/shared/nnm/databases/custompoller/export/final # find . -mtime +365 -type f | xargs rm
Check the usage is under the size limit:
du -hs . 649M .
