 Posted: Wed Nov 15, 2006 7:57 am Post subject: get running services? |
 |
|
Hi all,
I'm trying to write my first cron job.
I'd like it to send me a weekly mail containing the following info:
- uptime got it
- mem usage / mem free
- disk space used / diskspace total
- httpd running and live got it
- mysql live got it
- sshd live got it
- mailserver live got it
I'm not sure how to get to get this info.
Help in this area would be nice.
Here is the code for anybody interested:
| Code: |
#!/usr/bin/perl
# Status Report Generator
# by Jorge Schrauwen 2006
# info gathered at the gentoo forums
sub checkservice{
$srvname = $_[0];
$srvout = `/etc/init.d/$srvname status | grep -i started`;
if(length($srvout) == 0){
return "| $srvname: " . " " x (16-length($srvname)) . "stopped |\n";
}else{
return "| $srvname: " . " " x (16-length($srvname)) . "running |\n";
}
}
open(SENDMAIL, "|sendmail -t");
print SENDMAIL "From: \"Server Reporter\" <>\n";
print SENDMAIL "To: youradress\@domain.tld\n";
print SENDMAIL "Subject: System Info\n";
print SENDMAIL "Content-Type: text/plain\n\n";
print SENDMAIL "Report Date: " . `date -u` . "\n";
print SENDMAIL "+" . "-" x 18 . " System -+\n";
$memstr = `df -h -t ext3`;
$memstr = substr($memstr, -7, 4);
print SENDMAIL "| DiskSpaceUsed:" . " " x 7 . "$memstr |\n";
print SENDMAIL "| " . "-" x 25 . " |\n";
$memstr = `cat /proc/meminfo | grep -i memtotal`; chop($memstr);
print SENDMAIL "| $memstr |\n";
#$memstr = `cat /proc/meminfo | grep -i memfree`; chop($memstr);
$memstr = `free -m -k | grep -i buffers/`; chop($memstr);
$memstr = substr($memstr, -7);
print SENDMAIL "| MemFree" . " " x 8 . $memstr . " kB |\n";
print SENDMAIL "+" . "-" x 27 . "+\n\n";
print SENDMAIL "+" . "-" x 16 . " Services -+\n";
print SENDMAIL checkservice('apache2');
print SENDMAIL checkservice('mysql');
print SENDMAIL checkservice('named');
print SENDMAIL checkservice('sshd');
print SENDMAIL "+" . "-" x 27 . "+\n\n";
print SENDMAIL "+" . "-" x 19 . " Hosts -+\n";
[b]opendir(HDIR, "/home/");[/b]
while (my $file = readdir(HDIR)){
if(($file ne '.') and ($file ne '..')){
if(-d "/server/hosts/$file"){
print SENDMAIL "| $file" . " " x (25-length($file)) . " |\n";
}
}
}
print SENDMAIL "+" . "-" x 27 . "+\n";
print SENDMAIL ".\n";
close(SENDMAIL);

Don't know how to get it to send you the email, but to find out the status of a service run `/etc/init.d/<service> status`.

doh so simple! thanks this puts me another step closer!
I was thinking of going the netstat way and parse the output but his is 100x simpler!

- mem usage / mem free
cat /proc/meminfo
- disk space used / diskspace total
df -h
this is not strictly diskspace, rather filesystems, but might be what you want |

perhaps? The man pages are your friends... 
[edit] for mem usage, is 'free -m' better for you?[/edit] |

And, if your df, like mine, doesn't support a --format option, you can use | Code: | | df | awk '{print $5}' |

Mine does:
| Code: | # uptime
14:00:15 up 26 days, 20:47, 0 users, load average: 0.00, 0.00, 0.00 |

Thanks for all the help I'm done now. I'll update my main post with the code for other people interested in this.

Mine reports this aswel, I was looking for something along the lines of
0 days, 2 hours, 53 minutes, I just left it out since it seems to vary in how it displays it depending on the uptime -_-
