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. It supports email alerts and SLA
monitoring out of the box, and whatever you can script. The system is
programmed in plain (Bourne) SH, and made 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 the 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.
Each agent creates simple (static) HTML pages with full and condensed
status reports on each system, allowing simple local checks.
