fpmmm & Zabbix

Hello,

I installed fpmmm 1.0.1 to my system and try to start it with zabbix-agent (UserParameter=FromDual.MySQL.check,/opt/fpmmm/bin/fpmmm --config=/etc/fpmmm/fpmmm.conf). Trigger fpmmm Agent is down not working, and all data update with 10 minutes interval or doesn't update at all.

I receive this in fpmmm log:

28964:2017-02-21 12:19:18.812 - ERR :   Agent was running for more than 60 seconds (now: 2017-02-21 12:19:18, mtime: 2017-02-21 12:09:18). Killing it now! (rc=1101).

One interesting thing, when i run in console any fpmmm.php command i see additional "\n":

$ ./fpmmm.php --version

1.0.1

Maybe that is the problem

Taxonomy upgrade extras: 

Hello Vadim

Thank you for your suggestion. I am pretty sure that the empty line is not the problem. But I admit that it is a bug and it will be fixed in the next release (in fact it is already fixed in our internal revision 763). But it is IMHO not critical and will not affect your work.

# ./fpmmm-1.0.1/bin/fpmmm --version

1.0.1

# ./fpmmm-rev763/bin/fpmmm --version
rev763

# ./fpmmm-1.0.1/bin/fpmmm --config=/etc/fpmmm.conf 

1
# ./fpmmm-rev763/bin/fpmmm --config=/etc/fpmmm.conf 
1

What in fact is more relevant is the log file:

 7523:2017-02-24 08:41:38.432 - INFO: FromDual Performance Monitor for MySQL and MariaDB (fpmmm) (1.0.1) run started.
 7523:2017-02-24 08:41:40.941 - INFO: FromDual Performance Monitor for MySQL and MariaDB (fpmmm) run finished (rc=0).

 7723:2017-02-24 08:41:53.136 - INFO: FromDual Performance Monitor for MySQL and MariaDB (fpmmm) (rev763) run started.
 7723:2017-02-24 08:41:55.526 - INFO: FromDual Performance Monitor for MySQL and MariaDB (fpmmm) run finished (rc=0).

It shows that both versions run fine. So the problem must be somewhere else! The symptoms you described looks like the fpmmm agent died without leaving any notice... We have to find, where this is. I thought we have fixed all theses situations but it looks like we did not get all of them!
Can you please set LogLevel to 4 and send us the output of the dying fpmmm agent?

Thanks, Oli

Hello, thank you for reply.
1) About additional "\n" - in myEnv.inc file, in the end 2 empty lines.
2) Problem was in zabbix-agentd.conf. FPMMM need more time to run. So I add "Timeout=30" variable, to fix the problem

Also, set in php.ini variables_order = "EGPCS" for all server(i don't have dedicated server for mysql) is not good idea. So i changed first string of fpmmm.php to this #!/usr/bin/php -d variables_order=EGPCS

In debug logs i see something strange:
15604:2017-03-01 21:46:33.251 - DBG : Check connection to zabbix server.
15604:2017-03-01 21:46:33.253 - DBG : /usr/bin/zabbix_sender --zabbix-server XXX.XXX.XXX.XXXX --port 10051 --host 'my-server' --key FromDual.server.check --value '1' -vv

15604:2017-03-01 21:46:33.385 - DBG : Connection to zabbix server seems OK.

key FromDual.server.check is not exist in template ( i use zabbix 3.0 templates). Can you check it?

Hello hranitel

Thanks for your comments.

to 1) it will be fixed in next release in fact it is already fixed in rev763.

to 2) If the fpmmm/Zabbix agent in total takes more than 30 seconds something (with your network?) is wrong. Enable the LogLevel to 4 and check where the time has gone. We had something already earlier with network issues.

to variables_order: Your suggestion is considered and will be introduced into the next version.

to key FromDual.server.check: Something similar I have seen last week. Is it possible that you configured a SPACE in your fpmmm host or database name? That would explain it. As a workaround use a hostname without a SPACE (bad behavior anyway!) Never the less I think this should be considered a bug and must be fixed.

My suggestion is that the fpmmm when user with zabbix agent dot have enough time to complete all cycle. Zabbix show me "Timeout while executing a shell script." on FromDual.MySQL.check variable.

I don't have space in hostname. This is my fpmmm.conf:

Your log file does not show any reason:

6644:2017-03-08 23:13:02.115 - INFO: FromDual Performance Monitor for MySQL and MariaDB (fpmmm) (1.0.1) run started.
6644:2017-03-08 23:13:02.809 - DBG : /usr/bin/zabbix_sender --zabbix-server

It took only 700 ms in the output. So this cannot be a reason for a timeout of 30 seconds.

I will check with your configuration file.
