Hi!

If you run script from command line, you should get output similar to this:

root@netxms:~# /opt/netxms/bin/hp_eva_collect_data.pl
EVA.Disk[7].loops.loop[2].loopname=loopb
EVA.DiskShelf[1].diskslot[2].name=diskslot2
EVA.Disk[7].objecttype=disk
EVA.DiskShelf[1].diskslot[6].diskid=080720072004000CCA65B9400000000000000000
EVA.Controller[1].datablocksize=512
EVA.Disk[3].rssindex=6
EVA.Controller[1].controllername=Controller 1
EVA.Disk[1].disktype=fibre_channel_disk
EVA.DiskShelf[1].diskslot[11].name=diskslot11
EVA.DiskShelf[1].cooling.fan[2].firmware=80.1
EVA.DiskShelf[1].diskslot[5].diskwwn=2004-000c-ca2a-f588-0000-0000-0000-0000
EVA.Disk[8].operationalstate=attention
EVA.Disk[7].diskgroupname=Default Disk Group
EVA.Disk[3].operationalstatedetail=member_attention

... and so on. Do you get it?

Hi!

Alarm generation and actions are different things. For generating alarm you do not need an action - it's just special attributes in event processing policy rule. To set rule to generate alarm, do the following (assuming you already have rule object called "rule" of type EventProcessingPolicyRule):


rule.setFlags(rule.getFlags() | EventProcessingPolicyRule.GENERATE_ALARM);
rule.setAlarmMessage("%m");  // it's an example, you can specify your real alarm message here
rule.setAlarmSeverity(0);   // specify your severity
rule.setAlarmKey("");   // specify alarm key


and to set rule to terminate alarm:


rule.setFlags(rule.getFlags() | EventProcessingPolicyRule.GENERATE_ALARM);
rule.setAlarmSeverity(Severity.UNMANAGED);   // Severity UNMANAGED indicates alarm termination rule
rule.setAlarmKey("");   // specify alarm key


Also, you can take a look at property pages in nxmc-epp plugin in management console.

No, it is not necessary. Empty main() will be created by script compiler if it was not defined explicitly.

Just added "rename script" function to the Java console.

when will the java console include all the old features of the native console ?

I hope that version 1.1.8 will be able to replace legacy console completely. There are no much functions left.

Hi!

There are some confusion caused primarily by giving script itself and a function inside this script the same name. In "use" operator you should use script name (you can think of it as of virtual file name) - the one you see in script list in the library. Then, you can call functions from that script using their respective names - name of the function may or may not be identical to script name. Note that each script has it's own main() function, even if you do not declare it explicitly, so you cannot call main() function of another script. One script may provide multiple functions, like in this example:

Script in the library called "MyScript":


/* function 1 */
sub f1(p)
{
   println "f1 called with parameter " . p;
}


/* function 2 */
sub f2(p)
{
   println "f2 called with parameter " . p;
}


and then you use it in some other script:


use MyScript;  /* load script from library by it's name */

f1(1);  /* call function f1 */

f2(2); /* call function f2 */


Script above will produce output


f1 called with parameter 1
f2 called with parameter 2

I would like to know the problem is due to the web service stop or the web service is started but can't response (maybe Apache daemon is dead) or due to the programming failure or the web page is changed by crackers and so on.

You should monitor multiple things and react to them differently. First, you should monitor state of Apache service via System.ServiceState parameter.  If it is not running, you can automatically restart it using actions. Also, you probably should monitor that your web server responds correctly to HTTP requests. You can done it by creating network service under web server node, or by using ServiceCheck.HTTP agent's parameter. Search the forum, there should be instructions about network service configuration. Also, if you have static web pages, you might want to monitor that they are not changed by using ESC subagent - it provides checksum calculation for web pages.

You should not have function main() in library script. Try to change it like this:


sub CISCO_Config_Event_Config(e)
{
    switch(e)
    {
    case 3: return "running";
    case 4: return "startup";
    }
}


It is strange that server crashes. I'll try to reproduce it myself.

Best regards,
Victor

Parameters can be passed to subroutines like that:


sub main()
{
   f(1, 2);
   f(3, 4);
}

sub f(p1, p2)
{
   println "parameter 1 is " . p1;
   println "parameter 2 is " . p2;
}


If you have multiple parameters which needs to be converted using same function, you can create separate script in the library containing this function, and call it from different small scripts. For example, create script called "convert" with function "convert":


convert(p)
{
   // do conversion here
   return converted_value;
}


then create scripts like that for each parameter:

convert_p1:


use convert;
return convert($event->parameters[1]);


convert_p2:


use convert;
return convert($event->parameters[2]);


and so on.

Hi!

Currently it is not possible - server always calls main() subroutine when expanding %[] macro. I can add an option to specify parameters and/or entry points to these scripts - in 1.1.8 or 1.1.9, depending on how fast I will fix other things from to-do list.

Best regards,
Victor

Sorry, I forgot to mention it - in 1.1.x correct configure option is --with-webui instead of --with-nxhttpd.

Best regards,
Victor

If I understand you need correctly, you need script which will convert numeric codes into strings, right? Then you can do the following:

Create script in script library, with some name, let's say "convert" (here I assume that you need to convert event's parameter %2 into text - otherwise change index in parameters[] accordingly):


switch($event->parameters[2])
{
   case 1: return "test";
   case 2: return "test2";
   // and so on...
}
return "unknown"; // default value


and then use it in a message like %[convert]

Hi!

It's a bug. Unfortunately there are no workaround, you have to wait for version 1.1.8 with a fix.

Best regards,
Victor

Yes, that's correct.

Best regards,
Victor

It's fixed already in the trunk, so 1.1.8 will not have this bug.

Victor

Try to use netstat -atnp command - then you will see what exact process keeps this port open.
