WYAE - MoSShE - Lightweight, secure server monitoring

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 219 checks on 2 servers monitoring 6 systems - on average 36 checks for each system. 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 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.

Requirements

for each system: Unix Shell (Bourne-SH, BASH, Busybox) standard Unix text tools (fgrep, cut, head, mail, ...) "netcat" networking tool for additional checks (only if performed): "dig" for DNS check "free" memory display for memory check "lpq" BSD(compatible) printing for printing check "smbclient" for samba check "snmp" networking tools (especiall "snmpget") for SNMP check "mbmon" for motherboard checks (CPU temp, fan speed) /proc/mdstat for Linux SoftRAID monitoring for web interface: webserver
