Nagios Support Forum

Dear All,

Apologies if i violate any of the forum rules, As i am a noob to Nagios Forum and the product itself.

So, I have the following situation.

We were using CA as the monitoring tool for our servers i.e (150+ ) windows servers, we are now in process of phazing out CA due some internal constraints. So after searching around on google and reading the reviews about Nagios. We are in process of evaluting Nagios and we have following concerns /queries.

1. We have mix of Domain, Workgroup and DMZ servers accross 3 geographical sites --> Would i need a Nagios XI installed on every site or it can be a single server monitoring servers on all three sites.

2. Nagios has Agent Based Monitoring, We would need to install WINRPE Agent on every windows host that needs to be monitored --> Considering the servers kept in DMZ what all ports are need to be opened for windows and Nagios server to communicate and monitor successfully.

3.Local user user is created on Windows server with a non expiring password --> As per our hardening standard no user can have non expiring password, How does other people out ther using nagios tackle this situation.

4. Un-availability of customised reporting, Major report includes Availability and Trends --> For example if i need to prepare a report every month which show the disk, cpu and ram utilization (Highest, Lowest and Average) is there a way to achive this using default reports features or does this require some custom scripts written for the same?

5. Un-availability of Auto Discovery of the Drives --> While discovering the machines through the CCM nagios doesnt detects the drives automatically is there a way or work around that it can detect all the drives?

As long as those sites can route to your nagios xi server, you can monitor them with little trouble. If you cannot directly route you may need to set up a proxy agent between your networks in order to forward checks and check results back and forth.

2. Nagios has Agent Based Monitoring, We would need to install WINRPE Agent on every windows host that needs to be monitored --> Considering the servers kept in DMZ what all ports are need to be opened for windows and Nagios server to communicate and monitor successfully.

WinNRPE is very old and not supported anymore instead, in the last 4 or so years we have been using NSClient, and more recently NCPA as a replacement for that. Also, it is not required that you use an agent, you can run passive NRDP checks, WMI checks, or even SNMP traps from your windows systems.

3.Local user user is created on Windows server with a non expiring password --> As per our hardening standard no user can have non expiring password, How does other people out ther using nagios tackle this situation.

I suppose each admin has one way or another of doing this, at some point you would have to log in and reset the password.

4.

Yes you can do this, you can also create a dashboard with graphs or other information on your hosts/services and then schedule that dashboard as a report with the schedule page feature of Enterprise Edition "Top right hand side along the blue menu bar"

5. Un-availability of Auto Discovery of the Drives --> While discovering the machines through the CCM nagios doesnt detects the drives automatically is there a way or work around that it can detect all the drives?
