Description

Hi

Coinciding with the activation of the professional subscription we have detected a rise in CPU and resource consumption.

Is it due to normal behavior?

Is it some functionality that is activated automatically? Can we deactivate it?

We have also seen an increase in wrappers and the poller has been destabilized

You could tell us why these changes are due once the subscription with stable version is activated

More info relevant

This is odd, even if the Subscription version is polling more data, it's not polling significantly more data.

You can check the poller information views to see if the times have changed on all devices/modules or just specific ones.

It looks like perhaps the opcode caching is no longer working? You have very high cpu load, but no real change in poller time, which suggests maybe opcode caching has turned off and PHP got way slower.

Hi, sorry

I forgot to comment on a relevant topic

Also comment that apart from the increase in CPU, it was also detected that the disk and network part increased, in addition to observing that every Sunday has peaks in both network and disk

you could see in attach images

Regards

Please make and attach additional information about the device:

full snmp dump from device:

snmpwalk -v2c -c <community>  --hexOutputLength=0 -ObentxU <hostname> .1 > myagent.snmpwalk

snmpwalk -v2c -c <community>  --hexOutputLength=0 -ObentxU <hostname> .1.3.6.1.4.1 >> myagent.snmpwalk

If device not support SNMP version 2c, replace -v2c with -v1.

If you have problems with discovery or poller processes, please do and attach these debugs:
./discovery.php -d -h <device>
./poller.php -d -h <device>

additionally attach device and/or vendor specific MIB files
