– Syncing master server with remote pollers
– Assign devices to remote pollers
– Retrieve data from remote pollers (Pull mode)
– Transfer data from remote pollers to master server (Push mode)

Future updates will include:
– SSH based syncing (currently only direct SQL connection supported)
– RSYNC based sync with remote pollers ( scripts/plugins/templates …)
– Though data consistency checks
– Enhanced configuration for remote poller ( e.g. how long to keep data )
– Alerting in case of failures
– Failover capabilities

nmidAgent – Remote poller for Cacti

CactiLeave a comment0

We are excited to announce our upcoming Cacti® plugin is coming along nicely!

This new plugin will allow you to setup distributed Cacti pollers or “agents” with a central data aggregation and presentation server.

Remote pollers are using an on-demand mechanism to transfer polled data without the need to create NSF shares or permanent SQL connections to the Master system.

Features of this plugin:

  • No polling required from the master server ( though possible )
  • Distributed/Decentralized polling
  • Re-use of cacti internal functions
  • Remote poller still collects data even if no connection to Master servers exists. Data will be transferred at a later time.
  • All plugins work as designed on the master AND slave systems (thold, Reportit, CereusReporting …. )
  • Different polling times possible ( Master: 5 minutes, Slave 1: 1 minute, Slave 2: 5 minute, RRD file update on master: Every 30 minutes )
  • Data consistency/safety done using SQL methods/functions

Stay tuned and register for the newletter !

Upgrading Thold to the latest version

Cacti, TholdLeave a comment0

Sometimes during the upgrade process, not all required columns or table may have been added to the database. This error may manifest itself with an “Error: Save failed” message when trying to save changes to a device.

A possible fix to this is to manually call the upgrade.php script. To do this, go to the command line and change to the thold plugin. Then call the upgrade script:

cd /path/to/cacti/plugins/thold
php extras/upgrade.php

Then re-try saving a device. You will see the following messages:

Faking Low Thold Version
Running Thold Upgrade
Upgrade Complete

CSV Export in Cacti is not working

UncategorizedLeave a comment0

Sometimes it may happen that the CSV export from a Cacti graph is not working for large date ranges. You then may see an error 500 being returned by the browser. If this happens, you should try increasing the memory limit of your php instance.

This can be achieved by editing the php.ini file and changing the following line:

memory_limit = 64M ; Maximum amount of memory a script may consume

Try settings this to 256M:

memory_limit = 256M ; Maximum amount of memory a script may consume

and restart your webserver. On CentOS you can use the following command:

/etc/init.d/httpd reload
