Web-Based Monitoring

SouperComputer

I have a server here running on CC 3.0 home (FC2) and Id like more comprehensive harware/resource monitoring software. As the OS is more or less "headless", I need somthing web-based.

main things I need:

CPU utilisation (including breakdown of processes)
HD temp,
RAM utilisation (including breakdown of processes)
Things like fan speeds, voltages etc would be nice, but not needed as such.

looking on sourceforge, DTgraph looks like what I need.

Just wondering if anybody else has another suggestion.

mrtg perhaps...

dtgraph/mrtg is all very well but you still need to be pulling the actual data from somewhere.. if its a recent enough dell server (last 5 years) I'd use omreport above all else... otherwise take a look at lm_sensors and prepare to get your hands dirty.

example from omreport:

[relics]# omreport chassis temps
Temperature Probes Information

Main System Chassis Temperatures: Ok

Probe Name : System Temp
Reading : 24.0 C
Minimum Warning Threshold : 10.0 C
Maximum Warning Threshold : 45.0 C
Minimum Failure Threshold : 5.0 C
Maximum Failure Threshold : 50.0 C

Index : 1
Status : Ok
Probe Name : CPU Temp
Reading : 38.0 C
Minimum Warning Threshold : 10.0 C
Maximum Warning Threshold : 80.0 C
Minimum Failure Threshold : 5.0 C
Maximum Failure Threshold : 85.0 C

oh as for cpu/memory usage graphs your best bet would be a bog-standard perl script monitoring uptime (load averages) and vmstat (mem usage).. point the results at mrtg and you're away.

[edit] heres how simple graphing a 5minute load average is in your mrtg.cfg:

Target[load5]: `uptime|cut -d "," -f 5`

its a server machine, but not server hardware if you get me.

I wouldn't bother with lm_sensors for motherboard readings then... its not worth the effort... stick with cpu/memory figures.

mrtg is supposed to be good, I might check that out for a project thats coming up

ntop is what i use myself.

Big Brother - www.bb4.org - does some of what you're looking for also - bit of a dog on resources in my experience, but it does a good job.

Can't go wrong with SNMP/MRTG. I just pulled up the page from the proxy server in ucd http://garfunkel.ucd.ie (not sure if this works from outside ucd), and i can see Disks, CPU and Load Average. MRTG's great for monitoring squid and of course routing too.
