Zabbix definitely. Liked it so much that I started a service doing hosted zabbix now: http://tribily.com
Started that mainly because I got sick and tired of setting up zabbix over and over again with new clients and new projects every time :)
... witch Centreon of course!
My favorite is nagios based opsview.
with zabbix you can monitor everything
I use zabbix and Orabbix to monitor Oracle
more info here: http://www.smartmarmot.com
But frankly I think nagios is more powerful and easy to maintain(with the help of Makefile), zabbix is powerful but it still a little messing. So, I'm tryting to build an enhanced zabbix release, details is available here - http://www.admon.org/
I think that ZAbbix is now the most compresive tool
Zabbix is easy to use, implement, and customize. Operation is intuitive! Almost all functionality is included for both server and network monitoring. If something is missing for your environment, you can easily add new function or customize.
Zabbix will be a next generation OSS monitoring tool.
Zabbix has it all!
Agree with you!
For us here Zabbix is the most professional application for network monitoring. Works great!!!
Nagios is great, very solid but the architecture is aging.
Zabbix is the next generation. It has all the basics, monitoring, graphing, alerts, right out of the box. All configured from a decent, though a little obscure, web interface and stored in the sql database of your choice.
If you haven't looked at Zabbix 1.8, you should.
Big Brother -> Hobbit -> Xymon was our monitoring system of choice for almost 15 years, but it wasn't developing/updating as fast as we wanted.
Evaluated hyperic, nagios, etc -- lots of great benefits but just couldn't get them to be as easily extendable, manageable, reliable, and usable as we needed.
Transitioned to Zabbix a year ago and are confident that it will serve us well as our base of monitoring infrastructure for the next 10-15 years. Thank you Zabbix devs.
Used to get Nagios but switched to Zabbix
Open source is a very good alternative in this downturn period
OpsView - based on Nagios with extended options
we prefer zabbix
If you haven't explored this, you should.
easy customizable with perl, small footprint
Because of the complexity of Nagios, I started my own monitoring system: Oculus (http://blog.friesoft.nl/software/oculus/). In version 0.12 now, should be production ready somewhere this year.
Until then, I actually don't monitor. As long as everything is working, there is no problem ;-).
I'm surprised that Xymon/Hobbit isn't in the list of choices, it's definitely my first choice.
Some time ago you published an article regarding "Ham Radio". I would like to get a copy of it. Do you have a fie about it or a hard copy of it.
i used to use cacti + groundwork/nagios,the best combination :D
I tried Nagios and found it very complicated.
To have graphics you have to add centreon.
I dont understand why Nagios is so popular.
Now i'm using Xymon/Devmon/BBwin, it's much easier to manage.
Our company started using zabbix for last 1 year and its doing pretty awesome job..Moreover we are installing new Mikoomi monitoring appliance ,its virtual appliance based on Zabbix.
We use Zabbix. It is flexible and suitable for medium and large environments. It is not very easy but if you want to build a custom build network monitoring system it must be flexible and scalable. Zabbix is.
The recently released Zabbix version 1.8.2 is simply awesome.
Nagios is great when you have time to set it up and maintain it. If you don't, take a look at an automated monitoring tool called LogicMonitor. Monitors everything for you by default - no configuration required. Not free, but neither is your time. Check out http://www.logicmonitor.com for more information and a free trial.
For most part we use Zabbix and Munin
and we still have MRTG.
You can't beat it for ease of configuration. I've tried them all and OpenNMS makes my life very simple. Very flexible configuration system.
We started using Nagios several years ago and I have learned how to write custom
scripts to detect SAMBA login failures and shell login failures. It is great. The security
model is simple and near impossible to hack.
See my notes
We were interested in Hyperic, but it's high pricing profile can't make us afford it..:(
I chose to use this to monitor live servers and office systems back in 2005, I really liked the simple install, easy to write addon agents and remote collectors, the usefull graphics helped immensely to diagnose performance of jav virtual machines, memory, cpu and request rates.
We even had it send alerts via sms to operations when certain limits, events were triggered.
Can't understand why it never gets featured.
Used for different things on networks e.g. Cacti for raw Bandwidth usage, Smokeping for WAN connectivity and alerting, Munin for host info and Monit for alerting host info, nTOP for local LAN data and OSSIM for IDS in a DMZ network.
I love OSSIM from Alienvault! Quite similar to Groundworks, but includes more applications.
I was looking for something simple. After some research I've chosen Munin which in fact is a graphing tool but already does some nice monitoring, too.
Monit I use where protocols and finer grading of alerts is needed.
netstat.php I wrote myself to have a simple "interface" (with red and green lights:) for my users + clients (something which I found even many of bigger solutions are lacking).
Nagios + Cacti
Mon has monitored my network for 13 years now, I think.
More a 'framework for scheduling monitoring activities and alerts'. A few lines of a script (usually perl) to return a 'this is working/failed' status, a script to generate alerts (via whatever mechanism you have... email, sms gateway, for a long while I had it dialing a numeric pager via modem), etc.
Simple and reliable, it's one of those packages that Just Works.
I use Zabbix
Zabbix FTW! 1.8.x branch is showing big improvements in stability, features, and php frontend
Wondering why Zabbix is not listed as an option.
Simple and extendable.
I have used Big Brother, and now use hobbit to monitor over 4000 devices across 430 distinct sites. Works great and the customization ability and extensibility is amazing. Anything you can check with a simple script can be monitored and graphed.
Switched from Openview long, long ago. Switched from BB long ago. Switched from Nagios+Cacti a couple of years ago. Am quite satisfied with Zabbix now, though it's alerting subsystem is not up to Nagios it is otherwise much simpler and more powerfull. We write python + zabbix_get scripts to do alerting. Main drawback, other than alerts, is that it's written in PHP.
Second place has to go to OpenNMS which has most of the features of the others but none of the upgrade / security / integration hassles (thanks primarily to Java).
OpenNMS of course.
Xymon | Hobbit since... forever!
Xymon and Cacti
