System monitoring system for linux?

Question

linux

There is a computer with Debian testing, it acts as a NAT, file storage, torrent distribution, etc. You need a simple monitoring system with a web interface, to monitor CPU load, hdd space, RAM, network interface load. Monitoring via web-interface. Desirable: easy - do not load cpu, available in debian testing repositories, easy to configure. It would also be nice if the program was in ruby.

Answer 1

1. rrdtool+homemade scripts
2. mrtg
3. cacti
4. munin
5. [other rrdtool-based...]
6. zabbix
I use the latter. For one server, overkill, of course, but for tens/hundreds/thousands, it's great.

Answer 2

Monitorix

Answer 3

According to the requirements, only Munin is suitable. But he has a problem - he does not know how to notify.
It also does not know how to scale graphics.
If you need notifications, then nagios. But he needs to be dealt with.
Monit is not a monitoring system, it is mainly for raising processes that have fallen for some reason.
PS I use munin for non-critical things - to review the status of systems, and nagios + monit for critical ones, such as a dns server.

Answer 5

Recently, on Habré, someone promoted their development. I liked it, a rare similar program with a human face. But in Python. There are repositories for debian. Ajenti seems to be called: habrahabr.ru/blogs/i_am_advertising/104911/
Unfortunately, the program is still only alpha, but people use it, they rejoice. I haven’t gone yet, so I’m sitting on cacti.

Answer 8

Tried different things. I settled on Zabbix. Monitors ~500 nodes (switches, wifi bridges, servers, etc.).

Answer 9

Zenoss, the interface has become nicer by the third branch. If you need superpowers, you can upgrade to the corporate version.

Answer 10

try cacti + plugins .... I have a dedicated virtual machine (256Mb ram, 1CPU, 20GB HDD),

if it is difficult, then you can write a bash script and receive in text form
