Trigger name or trigger comments with macro's

[rangeshgupta]

Hi,

I m monitoring the process with the help of snmp. Below is the OID of the process.

UCD-SNMP-MIB:: prIndex.1 = INTEGER: 1
UCD-SNMP-MIB:: prNames.1 = Process name, it can be any process
UCD-SNMP-MIB:: prErrorFlag.1 = INTEGER: 0
UCD-SNMP-MIB:: prErrMessage.1 = STRING:

So i have created a trigger for service down


Trigger Name:- Process 1
Expression:- {SNMP_LINUXrErrorFlag.1.last(0)}=1

If my trigger condition is true, In the GUI it will say Process 1 Status: Problem

I hv tried to put macros on Trigger name or the comment for getting the process name put its not working

Any buddy know the work around of it.

Thanks

Let me make my question straight forward:

1. Can we hv macro's on trigger name or trigger comment.
2. If YES, then can i hv an example of it.
3. If NO, Is there any work around of it.

Thanks

Plz try this,

Trigger Name:- Process {ITEM.VALUE1} has Error {ITEM.VALUE2}

Expression:- ({SNMP_LINUXrNames.1.last(0)}) & {SNMP_LINUXrErrorFlag.1.last(0)}=1

Trigger names can have macros, (which can have values of items in trigger expression.

here ({SNMP_LINUXrNames.1.last(0)}) is used just to show you the process name.

(for more info, refer List of supported macros in manual)

That would be nice.

Thanks vijay for valuable reply

I hv tried the expression you hv mention. Now i m getting the service name with the trigger name. But the expression status is always UNKNOWN.

Trigger Name:- Process {ITEM.VALUE1} has Error {ITEM.VALUE2}

Expression:- ({SNMP_LINUXrNames.1.last(0)}) & {SNMP_LINUXrErrorFlag.1.last(0)}=1


Then i hv change the expression to :-

Trigger Name: Process {ITEM.VALUE2} has Error {ITEM.VALUE1}

Trigger Expression: {SNMP_LINUX: prErrorFlag.1.last(0)}=1|{SNMP_LINUX: prNames.1.last(0)}


Trigger is working fine when error flag is 1
but
when it is 0 the trigger status is UNKNOWN.

Is there any string function, so that i can the evaluate string expression.

Thanks

Looks like it is expecting a condition on the second part of the expression.
Can you plz try this.

({SNMP_LINUX: prErrorFlag.1.last(0)}=1) & ({SNMP_LINUX: prNames.1.str(#@!)}=0)

There are string functions (regexp, str etc). Str checks if the argument we pass is matching the part of the string. We can try checking if the prName does not contain #@! (some junk text). I am not sure there would be a better way, but this should work.

Thanks dude it working

Final Expression

({SNMP_LINUX: prErrorFlag.1.last(0)}=1) & ({SNMP_LINUX: prNames.1.str('123455')}=0)

Hi,
How did you set up the trigger for SYSTEM.CPU.LOAD . Can you please help me in this.

Hi,

Subbu

For example you can use:

{T-Linux-OS:system.cpu.load[,avg1].avg(900)}>5) & ({T-Linux-OS:system.cpu.load[,avg1].avg(900)}<8

But I prefer to use:

{T-Linux-OS:system.cpu.util[,idle,avg1].avg(900)}<10 | {T-Linux-OS:system.cpu.util[,idle,avg1].avg(900)}=10

Hi,
Thanks for the reply , how do you create the trigger if the SYSTEM.CPU.Load reaches to 95% for windows Servers.

You can use:

{T-MS-OS-Windows:perf_counter["\Processor(_Total)\% Processor Time"].avg(300)}>95

We are calculating the CPU load instead of that we are monitoring the load average.

Trigger expression:- {SNMP_LINUX:laLoad.1.avg(300)}>10

SNMP_LINUX : Template name
:laLoad.1 : Item Key (This item collect the load average of last 1 min)
avg(600) : Average value for last 10 minutes.

Thanks

Hi,
Thanks for the quick reply ,

{T-MS-OS-Windowserf_counter["\Processor(_Total)\% Processor Time"].avg(300)}>95

It means zabbix will monitor the load average for 5 mins , if load average is more than 95 then it will send a trigger . can you please give me a exact function name which i need to use to create a Trigger . As because iam taking it to the Live Production

[bashman]

{T-MS-OS-Windowserf_counter["\Processor(_Total)\% Processor Time"].avg(300)}>95

It means zabbix will monitor the load average for 5 mins , if load average is more than 95 then it will send a trigger .

Yes, it means that zabbix will do the load average for the last 5 minutes and if it's greater than 95% trigger will be set to TRUE (value will be PROBLEM) and if you have set an action with an email notification you should get a message.

can you please give me a exact function name which i need to use to create a Trigger . As because iam taking it to the Live Production

You can use "High CPU load" as a name for your trigger.

Hi bashman,
Iam very Thankfull to you , if have any doubts i will post a query here .if you don't mine can you please post me your email ID
