1.3.4 web application monitoring problem and feature request

[smiley76]

Hi,

I have just installed the latest beta version of zabbix.

Lot of features I have missed from 1.1 has been added and this looks really nice :-)


I did try out the webapplication monitoring and did stumble at some problems.

1. I added a new Scenario with no variable specfied and 60 seconds update interval.
2. I added a new step with name and URL and no post or Required variables.
3. When I click the Save button zabbix_server and mysqld goes crazy (both takes 50% CPU each)
4. checking the mysql.log I see a loop of these SELECTs:

692867 Query select count(*),min(nextcheck) from httptest t where t.status=0 and mod(t.httptestid,5)=3 and t.httptestid>=100000000000000*0 and t.httptestid<=(100000000000000*0+99999999999999)

and it seems like the application never tries to contact the URL I have added.

If I run the above query I get this back:

+----------+----------------+
| count(*) | min(nextcheck) |
+----------+----------------+
| 0 | NULL |
+----------+----------------+
1 row in set (0.00 sec)

and output from zabbix_server.log:

19272:20070330:115643 Nextcheck:0 Time:1175248603
19272:20070330:115643 No sleeping

and then the feature request.

the application I'm going to monitor has a bunch of <input type="hidden"> values that I would need to use in step 2. I couldn't find a way to grab this data from step 1 and post it to step 2. So maybe an "include all input hidden" feature is needed.

Thanks for reporting your problem!

As for the feature request, this will be implemented at some point.

Actually.. I have solved the problem.

Curl and Libcurl was installed but not Libcurl-dev so the zabbix_server didn't get compiled with libcurl. (Configure script didn't complain about it)

And for anyone else that gets this problem:

make sure libcurl is installed with development headers + that zabbix_server is built with --with-libcurl




Thanks.

I believe it is fixed in 1.3.5.
