Cacti poller runs very slow

Post by hakiki »

I installed cacti version 1.2.27 with spine on an RHEL environment, then migrated data from other system with older cacti version (0.8.8h). Then I found out that the poller on new system runs very slow that it exceeds 298 seconds every polling cycle.

Here's steps I did:
1. Install and configure cacti + spine ver 1.2.27 on new system (RHEL 8.10)
2. restore mysql dump + migrate RRD files from older system (cacti + spine ver 0.8.8h, centos 6) to new system

Here's logs from the new system

I use crontab to run the poller

Code: Select all

[root@mrtg-backbone ~]# cat /etc/cron.d/cacti
*/5 * * * * apache php /var/www/html/cacti/poller.php &>/dev/null
Strangely, when I run spine manually, it tooks only 33 seconds to run the poller:

Code: Select all

You did install 1.2.x and restore db from old version? So you have now php code 1.2.x and database 0.88? It is wrong.

1) Copy you old files include rra to new server
2) Import mysqldump from old version
= so you have now old cacti on new server
3) replace files from 1.2.x code
4) use new include/config.php, change here mysql user, password, ...
5) follow wizard
Let the Cacti grow!

Re: Cacti poller runs very slow

Oops sorry I think I missed some explanations on my steps:

Here what I did previously:
1. Install cacti 1.2.27 + spine on new system
2. Copy rrd files and restore mysql dump to the new system
3. Continue cacti installation wizard (the setup was directed to the upgrade wizard, which includes template upgrade and database conversion)
4. Finish the installation (upgrade) wizard.

Besides of different cacti version, there are some major version jumps between old vs new eviroment:
- OS: centos 6 vs RHEL 8.10
- DB: mysql 5.1 vs mariadb 10.3
- PHP: 5.3 vs 7.2

Also yesterday I realized that spine.conf didn't have correct permission set. I fixed that so now RRD files are updated but still with very long polling time:

Re: Cacti poller runs very slow

Post by macan »

Few ideas:
chmod +s /path/to/spine - for icmp ping
is selinux or apparmor used?
DNS is working well?
Enable boost
try rebuild poller cache
try change process/threads of spine
Let the Cacti grow!

Re: Cacti poller runs very slow

I had case of cacti slowness where I defined that mysql on new server had permissions to listen database on old server. Everything was very slow, even browsing through GUI. I removed those permissions and it stopped contacting old servers database. It worked normally after that.
So just as an idea to your case.
