Trigger from Web Monitoring Required Field

[benjaminconnelly]

I have created a Web Monitor to log in to ZoneMinder's XML skin and look for the required text <RUNNING>1</RUNNING> . I would like to create a trigger to alert me when either <RUNNING>0</RUNNING> is returned or if I understand the web monitor correctly when the step that <RUNNING>1</RUNNING> is required fails. How can I do this? I see that there are Items automatically created for web monitoring:

.test.in[Scenario,Step,bps]
.test.time[Scenario,Step]
.test.rspcode[Scenario,Step]

But not one for Required...

Also, just in case anyone is having trouble with POST I used this:

Variables:
{user}=username
{password}=password

Post:
username={user}&password={password}&action=login

Have a look at web.test.fail.

That doesn't seem to be what I am looking for. web.test.fail returns an integer based on the number of steps that fail.

I want to use the output of XML based on the Required fiels. <RUNNING>1</RUNNING> means the apps is running, <RUNNING>0</RUNNING> means the app has stopped and should be restarted. Can this be done? Am I going about it the wrong way?

First of all, the implementation of web scenarios isn't ideal. You want an item that explicitly captures that the page content hasn't loaded correctly. There isn't one. However, I think you can simulate this...

If you have a check to confirm that the httpd daemon is working correctly you can then "assume" this (pseudo-code):

if (web.test.fail(scenario) & http protocol is up & data has been received for scenario)
then
assume that page has errored
fi

But really, if you want more control then you'll need to use an external tool like selenium and push the data back to the server via zabbix_sender. Also, if you have specific requirements for web scenarios I recommend that you raise a feature request.

HI Benjamin,

In that case i set up an item:

Type: Zabbix Agent
Key: system.run[curl <put your parms here>]
Type of Information: TEXT

And then put a trigger on the result!

I was able to do a curl POST and then grep with Perl expressions turned on as sh did not love awk or sed or cut very much. I did this as a userparameter and then created an action if less than 1 was returned.

Thank you both for your ideas. I have learned this last two weeks there is 30 ways to do the same thing in zabbix.

Here is the userparameter if anyone is interested. This will cut output between XML output.

curl -s --data 'username=blah&password=blah&action=login' 'http://192.x.x.x/xmlpage.xml' | grep -Po '<XMLTGAG>\K.*?(?=<.*?>)'

Yay for Perl regex in grep!
