Cacti Graph Brakes issue.

[tumnahi232]

so should I be checking my cpu? Or would it be something like adjusting the settings on the poller page? I did check my cpu earlier and was typically under 15%, never spiking anywhere near max. I did already have several hundred hosts before the problem started.

[abhisekp34]

Any Suggestion ?

Since This Gaps in Graph is happening for mostly device !

Getting below ERROR on Cacti.log.

Do they Responsible for Cuts in Graphs ? if so, any solution do you have ?

Helps where scalability is important, or you have an under powered system from a Disk I/O perspective. You can read all about it in the Cacti documentation.

Since you are just learning, can you update to the 1.2.x branch? I'm noting the last error, and that looks like a corner case, though I'm taking notice. Updating to the 1.2.x branch is pretty easy as long as you have not installed Cacti from a distribution.

Code: Select all

cd /var/www/html
git clone -b 1.2.x https://github.com/cacti/cacti.git cacti-develop
/bin/cp -frp cacti-develop/* cacti
chown -R apache:apache cacti

The refresh your browser using F5, the upgrade will commence.

[TheWitness]

These warning are fixed in the 1.2.x branch now. The "direction" undefined index was fixed after the 1.2.18 release already.

[abhisekp34]

root@grwcacticpe01 # pwd
/var/www/html
root@grwcacticpe01 # git clone -b 1.2.x https://github.com/cacti/cacti.git cacti-develop
-bash: git: command not found
root@grwcacticpe01 #


Command is not working !

Please install git.

Getting below -nan values in rrd files.

Any Reason ?

As there is no ERRORs for this Device. Device is Up. Even Manual SNMP Connection is working. I can see the data by connecting SNMP with Specific OIDs
