Munin VS Zabbix

I rediscovered Munin. To my surprise it is written entirely in Perl. I remember Munin from years ago... it still seems healty and maintained and lies ready on your Deb-Repositories. So I followed the Easy Install Guide... which really is easy, but fails to mention that you need to install your own HTTP-Server to serve the HTML-reports.

A bit of background, which may make understanding my choices in this lib easier: Munin is a resource monitoring tool using rrdtool, usually run in a Server/Client Setup. The client accepts plugins which are just executables in a directory. Usually written in a scripting language, but it actually doesn't matter. Data is fetched every 5 minutes, plugins are first run with a config argument to spit out a munin graph config, followed by a run without arguments to present data. To support higher resolutions than just "every 5 minutes", graph config can contain config to tell munin one collects it every second. Then the fetching part needs to run as a daemon, writing a cache somewhere which gets output when munin wants the data.

When you do not have enough power you would get errors because looking up the plots would simply fail. Sounds more that there is one disk which is slower. I had one 2TB external usb which was really slow and the latency of lookups was through the roof. Are you on linux ? Then install munin-monitoring.org it shows latency of the disks out of the box.

what os ? on linux install https://munin-monitoring.org/ it will give you disk latency information.

I'd say give Munin a try.

Zabbix

Zabbix is a comprehensive open-source monitoring solution designed for real-time monitoring and management of various network components, such as servers, networks, and applications. It excels in data collection and processing, enabling proactive monitoring for early issue detection and resolution.

The PHP core package is offered as pre-compiled binary via Ports packages system. In addition, important softwares such as extensions, Composer and PECL libraries are available. So are frameworks such as NextCloud and Zabbix.

Prometheus is a great way to go, however you need to invest time in writing all the alerts. This was a daunting task for us, because we have too many vendors and device types.. we instead went with zabbix, which is a free open source platform similar to Orion. Quite easy to setup. All the device templates for monitoring alerting are provided by the community. There is a grafana plugin which integrates with Zabbix, so you can build beautiful dashboards in grafana while using the polling and alerting logic in zabbix. You can also use grafana OnCall via a zabbix integration. Phase1: You could move to zabbix. Realize cost savings without investing time. Phase2: learn and work on moving things to Prometheus slowly. edit: added links and some rewording

Setup Zabbix (https://www.zabbix.com/) and use SNMP (search for a template for your switches, chances are someone has created one) to pull throughput data from the switchport your proxies are connected to. This will graph them for you on a continual basis, you can then setup some triggers (alerts) that will flag over-utilization (say >80Mbps) for you, can generate an email or SMS alert based on that or just see it in the dashboard.

Look at setting up Zabbix (https://www.zabbix.com/) you can then do ping and latency tests to key hosts/endpoints and get packet loss and other variables in a graphical format. Also will allow you to setup monitoring to alert when there are known issues.

Check out Zabbix. Similar to something like PRTG (I see was already mentioned) but it is a free solution. Only cost is setup time and infrastructure.

now if its more metric data you are using and want to do APM, prometheus is your man https://prometheus.io/, want to make prometheus your full time job? deploy cortex https://cortexmetrics.io/, honorable mention in the metrics space, Zabbix, https://www.zabbix.com/ I've seen use cases of zabbix going way beyond its intended use its a fantastic tool
