Check hardware health of HP Proliant Servers by querying the iLO2/3/4 Management Controller.
Check hardware health of HP Proliant Servers by querying the
iLO2/3/4 Management Controller. No need for snmp or installation of
software.
Checks if all sensors are ok, returns warning on high temperatures and fan failures and critical on overall health failure.
A PERL plugin using Nagios::Plugin, IO::Socket::SSL and XML::Simple.

The plugin makes use of the HP Lights-Out XML scripting interface.
HP provides some PERL scripting samples:
http://h18013.www1.hp.com/support/files/lights-out/us/download/25057.html

Please note that the plugin shows only temperature sensors by default. Faulty hardware components are only listed if iLO returns error state.

Additional options:
-e: plugin ignores "syntax error" messages in the XML output. This may help for older firmwares.
-n: output without temperature listing.
-d: add PerfParse compatible temperature output.
-v: print out the full XML output from the BMC.
-3: support for iLO3|4
-a: check fan redundancy (only some models)
-c: check drive bays (only some models)
-o: check power redundancy (only some models)
-b: temperature output with location
-l: parse iLO eventlog
-b: show temperature with location
-x: ignore battery missing
-i: ignore NIC Link Down status (iLO4).
-g: display additional infos like firmware version and servername (may need increased timeout!)
-f: read input from file instead from iLO, possible to feed -v output to it
--sslopts: Defaults to 'SSL_verify_mode => SSL_VERIFY_NONE'. Use 'SSL_verify_mode => SSL_VERIFY_NONE, SSL_version => "TLSv1"' to avoid TLS Downgrade bug.

Howto:

First test if you can reach the management controller with a web
browser. The plugin only works if the https interface is reachable.

Install the PERL modules Nagios::Plugin, IO::Socket::SSL and
XML::Simple. Copy the plugin to your nagios plugin directory and make sure that the nagios user can execute it.

Put this in your nagios config:

define command {

command_name check_ilo2_health
command_line $USER1$/check_ilo2_health.pl -u $USER10$ -p $USER11$ -H $HOSTADDRESS$

}

Assuming that $USER1$ contains the path to the plugin, $USER10$ the
username and $USER11$ the password for the management controller.

Set up the appropriate services.

Hint: All management controllers have their own host definition in my nagios setup. So every Proliant Server with host_name foo has a management controller with host_name foo-ilo2.


Testing:
1. Dump iLO output with -v by redirecting to a file.
2. Edit the file and change some elements with to another condition.
3. Read the file with -f.

Bug reports:
Please send an email and attach the -v output. You may want to remove addresses and serial numbers from the file.

Trying to make it work but I get the error:

ILO2_HEALTH UNKNOWN - ERROR: Failed to establish SSL connection with XX.XX.XX.XX:443 SSL connect attempt failed because of handshake problems error:14094410:SSL routines:SSL3_READ_BYTES:sslv3 alert handshake failure.

Trying to run it from ubuntu 14.04 server using 1.60 version of script, against a ProLiant DL380 G7 server with iLO3 1.87..
Tried all the hints in the comments...
Any help would be appreciated

REally good plugin that has been working really well for us on all version of iLO ... except one DL380 which is running iLO4

I get the exact same error that is alos reported in January 2016 further don this thread:-

CHECK_ILO2_HEALTH.PL UNKNOWN - plugin timed out (timeout 15s)

Tried various options on the command line but as yet I've been unable to get this to work.
Thank you for the plugin.
It works with different options with most of my servers but one where I get the following:
ILO UNKNOWN - ERROR: Failed to establish SSL connection with 192.168.1.63:443 IO::Socket::IP configuration failed.

Any help is much appreciated.
Thanks
P.S. plugin version 1.60

If you get an error like this:
ILO2_HEALTH UNKNOWN - ERROR: Failed to establish SSL connection with :443 IO::Socket::IP configuration failed.
you have to change the tls value in the source code.
ILO3: change TLSv1 to TLSv11
ILO4: change TLSv1 to TLSv12
Tested with ILO3 v1.87+ and ILO4 v2.4+

This works well, after I patched it to use Monitoring::Plugin instead of Nagios::Plugin (that has now been removed because of a Nagios Enterprise dispute).

For v1.60 replace line 164 with
use Monitoring::Plugin;
and line 177 with
our $p = Monitoring::Plugin->new(
cool plugin, started with a minor "Nagios::Plugin" issue, replaced it with Monitoring::Plugin or Nagios::Monitoring::Plugin

and now it's working when run ./check_ilo2_health.pl -H -u -p

But because I have seperated IP (xxx.xx.xx.xxx), one for server interface and one for ilo interface (xxx.xx.yy.xxx) the check_ilo2_health.pl try to connect the server IP, do I really need to hardcode the ILO IP in the service definition or any surgestion for multiple IP

ex.

define host{
use ...
host_name ...
address xxx.xx.xx.xxx
_ILOADDRESS xxx.xx.yy.xxx
}

How would the service definition look for this?

It's a very good tool, working very well with ilo 2/3/4, but when I try to use with newest ilo4 version it's not working and i got the message:

CHECK_ILO2_HEALTH.PL UNKNOWN - plugin timed out (timeout 15s)

but for all ILO 2/3 and 4 firm version below 7 it's working properly. COuld you please help me to solve it?

./check_ilo2_health.pl -u username -p password -n -H 10.0.1.2 -t 60 -g

This failing with the error:
ILO2_HEALTH UNKNOWN - ERROR: Syntax error: Line #0: syntax error near "" in the line: "".

But withour -g i get:
ILO2_HEALTH OK - (Board-Version: ILO2)
Throws
ERROR: Failed to establish SSL connection
just as the ones below.
This is on FreeBSD 10-STABLE with OpenSSL 1.0.1p and IO-Socket-SSL-2.016. Setup worked OK on previous versions and so far have not figured out how to patch - not very good at Perl...
Works great on a lot of other combos of DL360/380 G5/6/7/8!
there is a problem with Debian 8 or rather openssl 1.x
to fix the problem you have to replace following:

new(PeerAddr => $host, SSL_verify_mode => SSL_VERIFY_NONE, $sslv3 ?
'SSLv3' ) : () );
---
> $client = new IO::Socket::SSL->new(PeerAddr => $host, SSL_verify_mode => SSL_VERIFY_NONE, SSL_version => $sslv3 ?
> 'SSLv3' : 'TLSv1' );

Hi,
i get the following error: ILO2_HEALTH CRITICAL - Drive Bay 1: Spun Down, Drive Bay 2: Spun Down, Drive Bay 3: Spun Down, Drive Bay 4: Spun Down, Drive Bay 5: Spun Down, Drive Bay 6: Spun Down, Drive Bay 7: Spun Down, Drive Bay 8: Spun Down

With this command:$USER1$/check_ilo2_health.pl -H $ARG3$ -u $ARG1$ -p $ARG2$ -c -o -d -n -t 60

Is this an unsupported Server for "-c: check drive bays"? ProLiant DL380 G6
First of all, thanks for this plugin! :)

I'm getting this error:
./check_ilo2_health.pl -H [iLO] -u [USER] -p [PASSWORD]
Bareword "SSL_VERIFY_NONE" not allowed while "strict subs" in use at ./check_ilo2_health.pl line 384.

How can i solve this?
Hello from Germany. We use this plugin for some years now and it is great. Current Version 1.56 is installed on our nagios system.

But at the moment we ran in a little problem since we installed the latest ILO 4 2.03 firmware HP submitted in january 2015. - Now nagios/the plugin shows a "Power_Supply Inlet Temperature Warning" on some ILO4 servers although the ILO4 itself is happy with all temperatures.

ILO2_HEALTH WARNING - (Board-Version: ILO=3) Power_Supply_2: Inlet Temperature Warning

Any ideas on that ?
byalaselva, January 14, 2015
It does what it says. Thanks
./check_ilo2_health.pl -H x.x.x.x -u user -p password

and i get:

ILO2_HEALTH UNKNOWN - ERROR: No parseable output.

needed to add SSL_version => 'TLSv1' to connect command to make it work after ubuntu upgrade.
if i did not do that, i got SSL error

$client = new IO::Socket::SSL->new(PeerAddr => $host, SSL_verify_mode => SSL_VERIFY_NONE, SSL_version => 'TLSv1') or die "error=$!, ssl_error=$SSL_ERROR";
Seems like the link posted for the updated version of this plugin is dead. Is there an alternative location to download from?
bytrevrobwhite, October 31, 2013
Good plugin, we had problems with it working on ILO4 for two reasons, one the ILO can take a while to return the results, fix this by specifying -t 120 (but make sure your timeout for nagios is long enough in the nagios.cfg).

The second issue is that the ILO4 often returns N/A in its temperatures, you can fix this as, by not trying to set the perdata if the value contains N/A follows:
Line 439:
if ( defined($cautiontemp) && defined($criticaltemp) && ($cautiontemp !~ m"^n/a$"i)) {
if ($criticaltemp =~ m"^n/a$"i) {
$p->set_thresholds(
warning => $cautiontemp,
);

} else {
$p->set_thresholds(
warning => $cautiontemp,
critical => $criticaltemp,
);
}

Hi,
I am trying this script (version 1.58) with an iLO4 (sw=1.30) DL360p Gen8.

I only get temperature values in return.

If I add the -n option it looks like:

./check_ilo2_health.pl -u USER -p PWD -3 -n -H 10.10.10.10 -t 60
ILO4_HEALTH OK - (Board-Version: ILO>=3)

Running it in verbose mode (-v) it looks like it can get info about fans, cpu etc.

But it is not displayed. Can this line in the verbose output be a hint what is missing?

Scripting utility should be updated to the latest version.

HAve anyone else had the same problem? Any idea what might be wrong?
Very excellent.

For me, with ilo2 and latest firmware, i have aa error :
ILO2_HEALTH UNKNOWN - ERROR: Failed to establish SSL connection with *****

Changed :
$client = new IO::Socket::SSL->new(PeerAddr => $host);

to:
$client = new IO::Socket::SSL->new(PeerAddr => $host,SSL_verify_mode => SSL_VERIFY_NONE);


After, check is fully ok.
