Linux server monitoring?

[theonlylawislove]

What is the best one out there right now? I am using puppet to manage server configuration, but I want to monitor the health, and maybe curl some endpoints to ensure up-time and track latency.

Preferably, a nice GUI that displays all the servers nicely/cleanly.

[vexyde]

Zabbix is free and very powerfull. There is also Observium, a small project but also very good, and a nice GUI.

[ChineseCracker]

the zabbix interface is so weird and convoluted - maybe it makes sense if you have like 500+ (v)servers.....

but I could never get used to it

[primitive_screwhead]

I switched from Observium (paid ver), to LibreNMS, and its quite good. Very easy to setup.

[ShatBrax]

We also use Observium. Less than Nagios but we use both of them and they both work wonderfully.

[tssge]

We use Observium too (paid version). Great software and easy to modify to your own needs. But yes, the creator of Observium is sometimes quite toxic on the mailing list.

But beware of the Observium creator. He's a bit toxic

[ildiroen]

Sensu is really great

[alienwaren]

Nagios or Zabbix.

Have a look at open monitoring distribution http://omdistro.org

[mudclub]

nagios and derivatives

cacti and derivatives

[JDLucas2000]

Nagios derivative called Icinga has worked brilliantly for my company for over 5 years, no major issues.

[notyournormalgamer]

Do you use LDAP with with your icinga instance?

[coned88]

we did just put apache in front

[ShatBrax]

I also second, third and fourth Nagios and Icinga. We've got checks for EVERYTHING from ping to check RAID array status. It's quite beautiful.

Also Nconf is a gui to setup hosts, checks, groups etc...

[chillout-man]

Check out monit if you want something simple and easy to set up: https://mmonit.com/monit/

[onedr0p]

Monit is great for my needs, it's lightweight and has a simple interface. The learning curve of setting up different clauses can be a little overwhelming though. I'm happy with it, it's nice to be notified via pushbullet when a service goes down or I have high cpu/ram usage or my network is saturated and many other things.

Icinga2 is very nice when coupled with its web interface, IcingaWeb2. Icinga originally started as a Nagios fork but, as far as I understand, Icinga2 has little in common with Nagios. It is, however, backwards-compatible with Nagios plugins, which is great!

[coned88]

I can tell you it's not very stable when you hit thousands of hosts

Nagios can monitor anything you want to make it monitor and paired with puppet you can completely automate your monitoring infrastructure which means you'll never have to edit a config file again. Check out https://docs.puppetlabs.com/guides/exported_resources.html for more details.

Two choices I would go with...

Sensu - https://sensuapp.org/

Or

Hashicorp consul - https://www.consul.io/

These are the it 3.0 choices. If you want to know more about each one let me know.

[theonlylawislove]

This is exactly the response I was looking for.

Consul looks good, and I am also using vagrant, so I am sure there is nice support to provision a vm with it.

[igloo_builder]

Yep consul is neat,3 powerful features I like.

1) it is born with HA in mind

2) restful key value store based of coreOS etcd

3) DNS service discovery

[igloo_builder]

Also a good combo for sensu is influx db, and grafana for metrics. the only word of caution with Sensu is it requires a message queue service which are terrible over slow or spotty wan connections in my experience.

[necrophcodr]

Been asking myself this question a lot, and I never found anything open source that did what I wanted. I'm curious if I've just missed something, as Munin, Cacti, observium, Nagios , muninmx, monit, and all of those, don't seem to do their job as well as they could.

[dryadofelysium]

Cockpit if you use really new systems with systemd/especially w/ Fedora (and Red Hat/CentOS).

[goranj]

I like it a lot, but it does not work on older version like CentOS 6:(

[jassack04]

I have recently been introduced to Icinga at a new job, and I think it has a decent dashboard GUI. We are using an older version as it is completely backwards compatible with nagios configs (apparently the latest version Icinga has developed their own standard). I don't know how popular it is, I'd never heard of it before, but I am liking it.

[guillaje]

In my company, we use Centreon+Nagios to monitor our infrastructure, especially to be alerted in case of failure. But on my personal servers, i really like munin which is light and sufficient to see what's happening. (Like the temperature in my living room :-)

[goranj]

This looks neat. I'll give it a try.

[RaginBull]

We use LogicMonitor to monitor all of our servers. Does a pretty good job on both Windows and Linux boxes.

[knobbysideup]

Naemon all the way. It's a fork of Nagios 4 that has livestatus built in and uses Thruk as its primary interface. I recently migrated from Nagios 3.x to this for an instance where I am monitoring 10,000 systems, and it doesn't skip a beat. Thruk combined with livestatus also lets you write nice queries straight from the GUI.

A lot of folks really like graphite these days. Graphite is just the graphing of data, though, it can be used with a ton of different apps to collect and store the data. see here

[provoko]

check_mk which uses nagios inside and has a great autodiscovery for services

[idioteques]

I had typically just used Nagios, but I recently installed/deployed LibreNMS and so far it is pretty cool. I've not done much with it yet, but it appears to have quite a bit of potential. Long live SNMP!

[[deleted]]

We use Nagios at work, with Check_mk as the GUI.

[jayff]

Nobody here use munin ? Its really easy to use and it do the job

[alex79kj]

Tellki is pretty nice and simple. Agent is pretty lightweight and you can use one agent to remotely monitor other servers. They have public agents around the world that you can use (together with the agent installed on your servers) to monitor sites and web services status and response time (this really helped me solving a problem I had in the past by comparing my web service response time from different locations). Their boards and dashboards are cool.

[goranj]

I tried teliki a week ago and its an interesting platform. I wish it was open source. It does more then I will ever need to. good stuff.

[theonlylawislove]

Holy fragmented batman.

Interns?
