Gaps in Graphs - Script Method

[pradeepspa]

Hello Folks,

I am monitoring the throughput of the device using custom bash script. My script will ssh into that device and get the stats. The issue is , its graphing but having lots of gaps in between.

cacti-graphs.JPG (38.28 KiB) Viewed 870 times

When I run the script manually , the total time it takes is between 3-6seconds. I have increased the poller for script from 25 to 50 seconds. At this point , I am not sure what causes this gap. Could someone help me out please?

Any one to help me in this ?

I would guess that the script still runs into timeouts, despite your increase of the maximum execution time of the poller script.
Have you checked the cacti log? (If necessary, after increasing the log level.)

Thanks for responding. I dont see any error in the logs (already in debug mode)

Any tweak would fix this?

With log level set to "MEDIUM" or higher, the return value of every data polling task is logged. Have you checked that your script returns reasonable values during the periods in which no data is graphed?

Another idea: have you checked in the Console in "Devices" that the device in question has been in the "up" state for a reasonable time? (I.e.: much longer than the time period from the last gap in your graph.)

I have increased the logging to "HIGH". where can I see the return value logged? from "/var/log/messages" or "usr/share/cacti/cacti.log"

It's should be in cacti.log, at least it's in /var/log/cacti/cacti.log on my system. Anyway, the log entries can also be found via the cacti Web GUI. (Console -> Utilities -> View Cacti Log File)

Here are some examples from my own system:
