1 - What is Host Grapher ?
Host Grapher is a very light and efective program to gather Host Statistics like cpu memory and processes. It has been written to be light and fast. One of the changes toward other programs is that instead of the server doing all the work of asking the clients for the information, its the client task to tell the server its own info.
There will be clients for Linux, freeBSD , solaris ,Windows and Tru64.
There will also a gateway program to include routers .
For an unix like machine porting should be easy and trivial.
The only think you need is perl installed and a working network.
The server runs on Unix . But porting it should be easy either,
You will need rrdtool to make it work.
Here is a Screenshot .
Better here is a Demo .
2 - How does it work ?
First install the server in one machine, install the client on the clients. On unix the client uses the crontab facility , on windows it will be installed as a service.
Security has not been an issue yet , so there is a simple general password autentication. Before the records are kept the client has to issue an registration request.
3 - What changed from version 1 ?
A lot the script are now a bit more complicated , the system now uses Plugins per graph.
It is quite simple to write ones own plugins and graphs , updating is now only
destrutive if necessary. Individual passwords can be assigned.
|PMEM||Memory per Process||$||$||N||N||N||N||N|
|PCPU||CPU per Process||$||$||N||N||N||N||N|
