If adding extra devices causes this problem and your server isn't heavily loaded, try adding more threads to your poller wrapper process.

The number after the poller-wrapper.py in crontab : 

root@omega:/home/observium/dev/update# cat /etc/cron.d/observium | grep wrapper
*/5   *   * * * root      python /home/observium/demo/poller-wrapper.py 1 >> /dev/null 2>&1
*/5   *   * * * root      python /home/observium/dev/poller-wrapper.py  5 >> /dev/null 2>&1
root@omega:/home/observium/dev/update#

Here you see I run one thread for the demo instance and 5 threads for the dev instance.

If you have instances overlapping, you might start getting gaps, so it's generally better to run more threads if you have the cpu/io throughput.

Hello,
if you're getting these gaps on many devices it may be that you added one that is responding slowly to snmp queries.
This thing happened to me when I added a couple of nexus 7000 with a old firmware, all the other devices graphs appeared in this way.
Try removing the last device you added, or increase their snmp timout.

You may also see high CPU on those devices.

Hope this helps,

Stefano

Dear All,

I am getting  gap in graph for many devices. Any idea what needs to done to fix this.
send output for:
./poller.php -d -m ports -h <this_host>

What changed before having problems?
Also, try increase snmp timeout (on device edit tab) to 2-3 sec (default is 1sec).

Help Appreciated. 

Thanks
