Dell Openmanage Server Administrator (OMSA) Email Alerts for Linux
Posted by: | CommentsEarlier this year I posted a script which sends email alerts from Dell servers using the alerting system built into Dell Openmanage. However, that script will only work on Windows systems.
A visitor to the blog called Steve has kindly posted some code on that post which enables the same functionality in Linux and I think it is worthy of its own post.
Before attempting to use the script you will need to download this perl script called sendEmail and that you have unix2dos installed.
The script accepts two arguments, which are setup or show.
“setup” will set the alerts action to the value of $alert_script which should be the full path to the script itself.
“show” will print the current alert settings for the system to the screen.
The code of the script is as follows, or you can download from here:
#!/usr/bin/perl
########
#
# Alter these setting to suit your system
$alert_script='/opt/asx_scripts/send_alert.pl';
$argument = 0;
$argument = $ARGV[0];
$omreport = '/opt/dell/srvadmin/bin/omreport';
$omconfig = '/opt/dell/srvadmin/bin/omconfig';
$sendemail = '/opt/asx_scripts/sendEmail';
$toname = 'name';
$fromname = 'name';
$domain = 'domain.com';
$tmp_path = '/tmp';
$mail_gateway = 'ip or name of mailgate';
$unix2dos = '/usr/bin/unix2dos';
#
#
if("$argument" eq "setup"){
set_available_alerts();
exit;
}
if("$argument" eq "show"){
display_set_alerts();
exit;
}
if("$argument" eq "help"){
print "If you need some help read the code\n";
exit;
}
unless($argument){
$desc=`$omreport system alertlog 2>/dev/null | grep "Description" | head -1 | cut -f2-9 -d: | sed 's/ //'`;
chomp($desc);
$date=`$omreport system alertlog 2>/dev/null | grep "Date and Time" | head -1 | cut -f2-9 -d: | sed 's/ //g' | sed 's/://g'`;
chomp($date);
$host=`$omreport system summary 2>/dev/null | grep "Host Name" | head -1 | cut -f2-9 -d: | sed 's/ //'`;
chomp($host);
$tag=`$omreport system summary 2>/dev/null | grep "Chassis Service Tag" | head -1 | cut -f2-9 -d: | sed 's/ //'`;
chomp($tag);
$attach="$tmp_path/$date.log";
`$omreport system alertlog > "$attach"`;
if( -f "$unix2dos"){
`$unix2dos "$attach" 2>/dev/null`;
}
$send=`$sendemail -f "$fromname\@$domain" -t "$toname\@$domain" -u "System Error: $host SvcTag: $tag Time: $date" -m "$host SvcTag: $tag Error: $desc Time: $date" -a "$attach" -s "$mail_gateway"`;
}else{
print "If you need some help read the code\n";
exit;
}
sub set_available_alerts {
$alert_list = `$omconfig system alertaction 2>/dev/null | cut -f2 -d"<" | cut -f1 -d">"`;
chomp($alert_list);
chomp($alert_list);
@split_alert_list = split(/\|/, $alert_list);
foreach my $alert (@split_alert_list){
$set_result = `$omconfig system alertaction event=$alert execappath="$alert_script" 2>/dev/null | head -1`;
chomp($set_result);
if("$set_result" eq "Alert action(s) configured successfully."){
print "Set Action:\t$alert\n";
}else{
print "ERROR Set didnt return expected value ($set_result)\n";
}
}
}
sub display_set_alerts {
$currently_set = `$omreport system alertaction`;
print "$currently_set\n";
}
exit;
A good way to test the script is to temporarily set the “Temperature Maximum” to something low like 12 to trigger an alert.
Unfortunately all of my Linux machines are virtual machines so I cannot test or modify this script, so if anyone wants to give me SSH access to a server running OMSA, be my guest. 
Again, big thanks to Steve for posting this and I am sure it will be useful to lots of people. This has also inspired me to make some improvements to my original Windows version.
Setting up email alerts from Dell Openmanage (OMSA)
Posted by: | CommentsDell Openmanage Server Administrator is a really useful tool for configuring and monitoring server hardware but it lacks built in E-Mail alerting or notifications.
The software is capable of calling external programs or scripts when a server alert is triggered so I have written a simple script that provides E-Mail alert functionality.
There are a couple of scripts out there that do similar, but I wanted something self contained and capable of using SMTP Authentication with an external relay.
The other problem with OMSA is that you need to go into each individual alert to configure the settings which can be very time consuming, I wanted a way to add them all automatically as I am going to install the script on a number of servers.
Once you have downloaded and extracted the zip file you will need to edit the variables at the top of the script to make them appropriate for your environment:
The variables at the top define the e-mail settings and are hopefully self explanatory. If a remote SMTP server is not specified the local machine will be used to send the E-Mail.
Below these you can to decide what events you want to be notified of, just comment out any that you aren’t interested in, e.g:
AlertConfig(0)="powersupply|Power supply failure"
AlertConfig(1)="powersupplywarn|Power supply warning"
'AlertConfig(2)="tempwarn|Temperature warning"
'AlertConfig(3)="tempfail|Temperature failure"
I have included every alert available in OMSA 6.2 on a PE T710, some of these alerts won’t be available on older versions or machines.
After you have configured the script, I suggest you test that the E-Mail options by running:
cscript dellalert.vbs testemail
You should receive a test e-mail, if not something isn’t working properly.
When you have successfully tested e-mail, configure OMSA to send alerts by running:
cscript dellalert.vbs setup
You will then see the script go through and setup all the appropriate alerts as per your settings. This process can take a couple of minutes as the “omconfig” command takes a while. This step will not work if you do not have OMSA installed.
Once this is done you should be able to see that the script has been added into OMSA:
Now you need to generate some real alerts to test the script properly. How you do this will depend on the capabilities of your server, I was able to disconnect the redundant power supply and have an alert generated almost immediately. I think opening the case will also generate an event, but I am not sure as I didn’t test. Hopefully you should get something like this in your Inbox:
Update: There is a new version of this script which is written entirely in Powershell and will work with Windows Server Core etc. Please visit :
