[colug-432] unix monitoring

[Rick Hornsby]

We're presently using Microsoft SCOM to monitor our enterprise (mix of Windows and Linux) ... and it's ... horrible.  There's simply no other way to describe the experience for a UNIX admin.  We've given up trying to automate the unix agent installation.  It's a broken in ways we cannot fix.

So we're pondering a better solution for our UNIX environment.  BMC Patrol is out - it's got big stompy feet and an even larger price tag.  We're looking at free/OSS options to cover ~1000 unix hosts, mostly RHEL and SUSE but some Solaris and AIX.

Start with the basics - CPU load, disk space, ports listening, processes running, etc - and have the ability to grow into application level monitoring.  It would be nice if the OSS version supported LDAP auth.  We plan to integrate the solution into our eventual server provisioning stuff that we're planning to build with Puppet.  It would also be nice if the dashboard was pretty.

For an idea, some of the ones we're considering are Zabbix, Nagios, Sensu, and PandoraFMS.

Zabbix - I have some past experience with 1.x and 2.0/2.2.  The web UI is a little painful.  Just now I quick-like spun up a Zabbix 3.0 instance --- and things on the dashboard are blinking.  No really, green blocks on the screen are blinking.  Please stop blinking, giant blocks.

Nagios - It's been around long enough to have earned a bad rep for basically being old, never very user friendly, and generally brittle by modern standards.

Sensu - It looks pretty?  Don't know much, but it's weird that the OSS version is Ruby but the enterprise version is Java?

PandoraFMS - Don't know much about this one.

What are you guys running?  It feels like there must be more options out there that we're not aware of.

thanks!
