WYAE - MoSShE - Lightweight, secure server monitoring


This Software is being retired.

Please look at its successor MoSheL


MoSShE (MOnitoring in Simple SHell Environment) is a simple, lightweight (both in size and system requirements) server monitoring package designed for secure and in-depth monitoring of a handful of typical/critical internet systems.

For example in a current setup I do 271 checks on 2 hardware servers monitoring those, plus 4 vServers and 4 other remote systems. MoSShE supports email alerts and SLA monitoring out of the box - and whatever you can script.

The system is programmed in plain (Bourne) SH, and to be compatible with BASH and Busybox so it can easily be deployed on embedded systems.

Monitoring is designed to be distributed over multiple systems, usually running locally. As no parameters are accepted from outside, checks cannot be tampered or misused from outside.

The system is designed to allow decentralized checks and evaluation as well as classical agent-based checks with centralized data accumulation.

Agent data usually is transferred via HTTP, so available web servers can be co-used for agent data transfer. Additionally each agent creates simple (static) HTML pages with full and condensed status reports on each system, allowing simple local checks.


for each system:

for some checks additional tools are necessary:
