Try changing the "zMaxOIDPerRequest" from 40 to 10 for those devices or in their Device Tree to see if that helps.

I do see a lot of Task mydevice skipped because it was not idle in the zenperfsnmp.log file. What causes this. are there configuration values I should set to fix this.

pings work ~1ms for each device. It's 10 out of 27 devices that have this issue including the zenoss server.

What version of SNMP are you using What OS is the Zenoss server What is the Zenoss server specs how many total devices are you monitoring

From the Zenoss server CLI, start a continuous ping to one of the devices that keeps timing out, let it timeout a time or two with SNMP and then check the results of the ping to see if any were dropped.

Using SNMP V3
Kernel = 2.6.32-358.el6.x86_64
RAM = 16G
CPU = 8 cores

27 devices are being monitored. Only ones with issue are linux devices.

will provide results of ping in another comment.

have you seen this post: http://community.zenoss.org/message/73439

I haven't really been able to find any info on it. Try lowering the OID's down to 5 and then restating zenoss

Thanks for the post. Hadn't seen that post. I have lowered the OID down to 5 and restarted zenoss. will see if that works for these devices. Will also request the infrastructure team to validate the engineid's of these devices as well.

I deleted all the devices that were having the issue except for the zenoss server but still getting timeout when getting performance info for the zenoss server. zenperfsnmp runs fine from command line.

Solved issue by switching to using SNMP v2c rather than V3.

Hi,

I am having the same issue and by changing to v2c doesn't solve the issue. I also tried to reduce maxoid's and it didn't work out for me. I came to foung that zenperfsnmp is configured to run for 6osec by default globally. Is there a way i can setup zenperfsnmp config for each device depending on device collection rather than doing trial and error method

Any answers will be appreciated.

Thanks

You don't say what version of Zenoss you are on For some long time (since 4.0 ) there has been a zSnmpCollectionInterval Configuration Property that you can set at either device class or at an individual device level,

Cheers,

Jane
