Recently I have switched from [MRTG](http://oss.oetiker.ch/mrtg/) + [Cacti](http://www.cacti.net/) + [Nagios](http://www.nagios.org/) + [Gnokii](http://www.gnokii.org/) to [Zabbix](http://www.zabbix.com/), and I
|
||
must say I’m more than satisfied with it. It can do anything the former tools
|
||
did, and much more. First of all, it can do the same monitoring as Nagios did,
|
||
but it does much more fine. It can check several parameters within one
|
||
request, so network traffic is kept down. Also, its web front-end can generate
|
||
any kinds of graphs from the collected data, which took Cacti away. Also, it
|
||
can do SNMP queries (v1-v3), so querying my switches’ port states and traffic
|
||
made easy, taking MRTG out of the picture (I know Cacti can do it either, it
|
||
had historical reasons we had both tools installed). And the best part: it can
|
||
send SMS messages via a GSM modem natively, while Nagios had to use Gnokii.
|
||
The trade-off is, I had to install Zabbix agent on all my monitored machines,
|
||
but I think it worths the price. I even have had to install NRPE to monitor
|
||
some parameters, which can be a pain on Windows hosts, while Zabbix natively
|
||
supports Windows, Linux and Mac OS/X.
|
||
|
||
So I only had to create a MySQL database (which I already had for NOD32
|
||
central management), and install Zabbix server. Everything went fine, until I
|
||
reached about 1300 monitored parameters. MySQL seemed to be a bit slow on disk
|
||
writes, so my Zabbix “queue” filled up in no time. After reading some forums,
|
||
I decided to switch to PostgreSQL instead. Now it works like charm, even with
|
||
the default Debian settings. However, I will have to add several more
|
||
parameters, and my boss wants as many graphs as you can imagine, so I’m more
|
||
than sure that I will have to fine tune my database later.
