Graphs missing data polling correctly

Nitr0 · Post by **Nitr0** » Wed Feb 20, 2008 12:01 am

I'm having an issue with my graphs. They all seem to have little slivers of white space where there is no data being transmitted, but there is data going through, I'm wondering how to make them solid or why they are not in the first place. Attatched is a picture to show what I mean.

Thanks

I'm also getting the same issues on localhost

Looks like the cacti poller is unable connect to devices every once in a while. Change the logging level in cacti to medium and watch it. When you get the gaps, whats going on?

I seem to have a lot of logs (in excess of 150MB) all filled with the following

02/19/2008 10:25:01 AM - SPINE: Poller[0] Host[23] ERROR: Empty result [10.1.101.68]: '/var/www/html/scripts/getCanopySmStats.pl 10.1.101.68 Canopy power'
02/19/2008 10:25:01 AM - SPINE: Poller[0] Host[23] DS[164] WARNING: Result from SCRIPT not valid. Partial Result: ...

Which makes sense because I know the PL scripts failed to work after canopy updated their SMs. Nothing specific to the empty values though.

1) increase the memory / timeout values in your php.ini config.

2) increase the timeout to the device(s) which are having problems.

Do you have the specific php.ini variables on hand?

Search is your friend...

memory_limit and max_execution_time

They are also displayed in Utilities -> Technical Support

Nevermind, I found them, still didn't change anything. Any other ideas?

You increased the timeout to the devices in Cacti which were having problems too?

Once again, look in your cacti log file when the gaps appear. Did the device go down? Was cacti able to retrieve data from them? getCanopySmStats.pl is not relevant (to me) because you didn't post graphs with them having issues. The two you posted are pure snmp queries.

Okay, re-did my cacti install. Only one device and localhost. Getting the following errors.

I suggest you stick with 5 min cron and polling for 0.8.7. re-set both of those in cacti's settings. Also make sure you only have one entry in your crontab invoking cacti.

I had them set to 5 but I'm getting the same errors.

RE-SET them both to 5 min.
