"Lightweight and Scalable, but Auto-Updates and Docs Need More Control"

3.5/5

What do you like best about LibreNMS?

It's a lightweight tool. As long as your devices support SNMP, LibreNMS will work. It's also very scalable. Review collected by and hosted on G2.com.

What do you dislike about LibreNMS?

Auto-update is baked into the software; you have little to no control over when updates are applied.

LibreNMS's documentation isn't always up to date with the current feature-set.

Some device's SNMP support is very lacking. Review collected by and hosted on G2.com.

"Great open source network monitoring tool"

5/5

What do you like best about LibreNMS?

LibreNMS offers all the features you can find on any commercial network monitoring system.

It's open-source, free to use, and a very active project with constant updates.

Also, it's easy to install if you use the containerized solution. Review collected by and hosted on G2.com.

What do you dislike about LibreNMS?

I can consume a lot of resources, especially CPU. So reserve the right amount of resources according to the size of your network (number of devices).

I you use the containerized implementation, you will not have problems with upgrades. But if you are installing the software directly on your SO, you may experiment issues.

So, make a backup before upgrading it. Review collected by and hosted on G2.com.

"Easiest network management system you will ever implement"

5/5

What do you like best about LibreNMS?

LibreNMS comes ready to work out of the box with many different vendors, Whether Cisco, HP, Juniper, or any other brand it's likely supported. It is full of features you may never need for any device and can be integrated with tons of plugins to help with configuration management and weather mapping. Did I mention it's open source, heavily documented, and supports a variety of installation methods? Review collected by and hosted on G2.com.

What do you dislike about LibreNMS?

It can be challenging to implement different plugins due to not having a lot of documentation or guides, which means you need to be technical to get some features out of it. I wish they had an all-in-one installation package that included all the necessary pre-requisites ready to go, such as a database. Review collected by and hosted on G2.com.

What problems is LibreNMS solving and how is that benefiting you?

We can quickly get information from multiple devices you would generally need to implement with a template. For example, in Zabbix, I would need to make a template to grab power statistics for a Netonix switch which, with Librenms, I only need to add in the device to be monitored. We also get alerts about UPS that we have set up through routers now easy to know when a building is on battery and have time to run to the site before running out of power.

"Very nice open source Monitoring tools"

3.5/5

What do you like best about LibreNMS?

What I like about Librenms is that I can add any device ( I have not found one that did not work) to its SNMP puller and get device information very easily. I can also add ssh and telnet information to Librenms to login into the network or server equipment Review collected by and hosted on G2.com.

What do you dislike about LibreNMS?

Like all open-source programs, if there is a major issue and you are not that strong in Linux, it can be hard fixing things. But there is a community for Librenms and so far it has not been an issue getting question answer or points you to the right direction Review collected by and hosted on G2.com.

Recommendations to others considering LibreNMS:

If you are looking for Network monitoring tools that LibreNMS can help with that. If you are starting in Linux and need to improve your skill, LibreNMS can help with that. LibreNMS has many tools that I don't use, and it is applied to network devices, computers, servers. Review collected by and hosted on G2.com.

What problems is LibreNMS solving and how is that benefiting you?

What i solve with Librenms is the following :

1. Getting CPU of network or server

2. Bandwidth graph of network or server

3. Alerts to email, Slack, and Opsgeinie

4. The ability to ssh to device and servers

5. It one system instead of multiple systems. Review collected by and hosted on G2.com.
