Nagios Support Forum

Hello Team,

Could you please let me know if we can do network updates like patch schedule and other network related updates using
Nagios XI?

We want to understand if Nagios XI can do network devices related updates.

Nagios XI does not have the capability out of the box to perform updates on a network. You could, however, use it to check whether certain machines have been patched. See the documentation linked below for an example of how check whether a Windows host has been patched.

Luckily, Nagios XI is highly extensible and has a large community of developers working to expand the functionality of the software. You may be able to find a plugin on Nagios Exchange that is able to check for certain patches and updates on Linux and Cisco devices as well.

Hello,

Thanks for your reply!!

Do we have such features available in Nagios Network Analyser?
As I knw network analyzer is mainly for network devices.

Can you please confirm if Nagios Network Analyzer gives the ability to script any configuration change, firmware upgrade, configuration backup in bulk and within seconds or minutes?

I do not believe that Nagios Network Analyzer can do those things out of the box either. Most of our software offerings are geared more towards monitoring, rather than being a full suite of tools for systems administration. However, the upcoming Nagios XI 5.7 release will contain added features for automating the deployment and management of Agents, like NCPA, on the network.

Let us know if you have any other questions.

2. Could you please recommended Node capacity ? Please give us a brief on hardware requirements.
3. Is Failover of nodes is possible in Nagios Enterprise ? if yes how it will work ?
4. Can we have centralized dashboard for all nodes under Nagios Enterprise license?
5. Is there inbuilt backup option available ?
6. Which Database will be there in Nagios XI? In-built ?
7. Is there limitation on DB capacity/operation?
8. Can we monitor Network Device for below parameters through Network Analyzer:
a. CPU/Memory/Disk utilzaiton
b. DMVPN certificate validity
c. Ping, Network bandwidth/ n/w analyzer
d. MPLS/VPN or other links
e. AccessPoints

9. Can we monitor the Network devices using sensors?
10. Can we use same hardware/common hardware for Nagios XI and Nagios Network Analyzer? Or we need different?

Please suggest!!

1. You can use the latest of the supported OS listed here:

https://assets.nagios.com/downloads/nag ... -Linux.pdf

I personally would recommend CentOS 7 latest.

2. Host many total hosts do you have? We generally estimate about 7 to 10 services per host. What would that total be for you once you're fully up and running?

This is very unique to your system/environment as we don't restrict which plugins you run.

See here:

https://support.nagios.com/kb/article/n ... g-523.html

3. There is not currently any built-in HA functilnality, a lot of customers use DRBD, see here:

https://assets.nagios.com/downloads/nag ... ios-XI.pdf

4. You would need Nagios Fusion for that:

https://www.nagios.com/products/nagios-fusion/

5. Yes, see Admin > Scheduled Backups, and here:

https://assets.nagios.com/downloads/nag ... ios-XI.pdf

6. MariaDB on EL7 local to the XI server, you can offload it if you want. see here:

https://assets.nagios.com/downloads/nag ... Server.pdf

7. We don't impose any limits.

8. Nagios Network Analyzer is for analyzing netflow data. Nagios XI would handle the other checks (doesn't do netflow like Network Analyzer).

9. What do you mean by that? You can setup mod_gearman and use external workers and put an external worker in each datacenter/location/etc:

10. All Nagios products should be installed on their own server, do not try to install multiple Nagios products on the same server, they are not meant to be run that way.


Additionally, you can get one free quickstart per product:
