[smokeping-users] Holes in graphs

[Eric Chatham]

Hi Peter,

Where is the Smokeping logfile located at?  I tried /var/log/messages, but I don't see anything in there for Smokeping.

Also, how would I setup multi-pollers, as you suggested?  If I did reset the step/ping configurations, how would that affect the RRD files?  How would I modify them?

Thanks, again. :)

Hi Eric;

Check your SmokePing logs to see if you're getting a message similar to "1 round of polling was longer than step" (or something similar, I can't remember the exact error at the moment).

If you are getting that message, then there are a few ways to fix it:

- Increase step time
- Decrease ping count
- Run multiple pollers and split up the hosts to use them.

Running multiple pollers if you're not already is probably the easiest fix, because changing the step or ping count will require modifying your RRD files.

- Peter

Hello,

Is there any way to minimize - if not get rid of - the holes in the graphs?  I've noticed that when a customer is no longer reachable with the FPing probe, we start seeing holes consistent in all the graphs.  Would increasing the step help correct this?  Right now, I have the step set at 120, and pings set to 20.  We monitor over 100 customers with Smokeping and we use two slaves (one slave in NY and the other LA).  Thank you for any advice on how to correct this.

Sincerely,
Eric Chatham
