Hi,
I'm looking for some monitoring tool. It should be multi-user, I mean that a single user can view only a limited host's group.
And it should be web based.
Any suggestions?
Thank you very much

I use nagios for monitoring. Nagios provides web interface.

I agree with the above poster. Nagios gives a pretty decent GUI and nice "one-stop shop" once you get it up and configured.

Another good tool will be Zenoss, it fits your needs and in my opinion easier to config than Nagios.

Nagios
Cacti
Zabbix

Just to name a few.

Some months ago I did a research on open source monitoring systems.
I sorted out systems that...

• are not maintained anymore,
• have a too small community,
• have no internationalization.
• have limited features (e.g. focussing only on SNMP)

Then I evaluated the following:

• Nagios
• OpenNMS
• PandoraFMS
• Zabbix

Each of them has a slightly different logic and approach. Nagios e.g. has a long history, but also a monolithic kernel and is difficult to configure (text files). PandoraFMS is a young system with a modern UI, but has some drawbacks in it's logic. OpenNMS is very mature, but seemed very hard to configure.

I decided for Zabbix, which has a lot of helpful features and a good performance:

• combines C backend and PHP frontend (MySQL or PostgreSQL database)
• configuration completely via web UI, featuring e.g. bulk changes
• configurable via API (does not yet include all items)
• configuration can be imported/exported via XML
• host group based permission system
• authentication internally or via LDAP (e.g. MS Active Directory)
• a very unique language for specifying alert triggers. You can realize trigger hysteresis, alarms on relative increase/decrease and much more with this language - without any plugin.
• built in data history incl. graphs (round robin database)
• data retrieval via agent, SNMP, IPMI
• host autodiscovery (IP)
• service autodiscovery (e.g. server hard disks, switch ports)
• can be extended via plugins / bash scripts / windows batch files
• nice apps for Android and iPhone

So far I am very happy with my decision. Of course every system has it's limitations, but Zabbix is actively developed, will always stay free (there is no "pro version") and is backed by a professional company that offers training, support, conferences etc.

I'm using OpsView. It has a good set of templates already in place and I'm very happy with it. It uses nagios and wraps in a DB for history and graphs. Use SNMP for various devices such as cisco, F5 and Brocade, also NMIS for granular details of a graph which lets me see data without spikes interfering.

As mentioned, Nagios is one of the major contenders. However, I really like this remake of Nagios called Icinga:

Its just a fork of nagios, but its much cleaner.

We also use observium for monitoring(not alerting):

And we use Ganglia in our cluster:

I can offer to use the tool Anturis http://www.anturis.com which offers a lot of monitoring features.

Hi

I've been using various monitoring tools for several years, and you are right in the comments you are doing.
If you are accustomed to using Nagios plugins, the best option is Icinga.
We are currently using in my company Pandora FMS ,it is a very young tool but is growing very quickly. Version 5 has nothing to do with the above. I'm talking to them for updating to their Enterprise version and they have told me that for version 5.1, they will get a compatible version for Windows. For us it is a great solution, since the methodology of our company, all systems are or should be Windows, and the installation of these Nagios, Pandora FMS tools ... we have to perform on the VM, and performance is always somewhat lower than on a real machine.
