2.4.2 Web Monitoring, Curl garbled output

[gleepwurp]

Hi Folks,


I have a Web Scenario that was working pretty well until recently, when the web scenario stopped getting valid web pages.

I'm able to use the string from the zabbix_server log to check my webpage through a web browser successfully, but when I enable debugging mode on the Zabbix http_poller, I see that the process is returning a small garbled number of characters ('^_<8b>^H') instead of the html output. Other web scenarios are working fine.

Here is an example of the debug log with output (see end of second line for garbled output):

4478:20141216:101215.291 process_httptest() go to URL "http://webpage.com/?username=monitoring%40bla.com&pwd=password%40bla.com"
  4478:20141216:101215.446 process_httptest() page.data from http://webpage.com/?username=monitoring%40bla.com&pwd=password%40bla.com:'^_<8b>^H'
  4478:20141216:101215.446 In int_in_list() list:'200' value:200
  4478:20141216:101215.446 End of int_in_list():SUCCEED

Has anyone ever encounter the same issue?

Thanks!

Could this be a translation error when reading parsing the HTML code into a character string?

Thanks for the reply Parasin!

However, I debugged over the weekend, and it seems that the web page is now reporting the data as "Content-Encoding: gzip", which explains the garbled output.

The current Zabbix Server (2.4.2 & 2.4.3) doesn't support the compressed web pages. A patch was issued here: https://support.zabbix.com/browse/ZBXNEXT-2475 by Maxim Odinintsev which actually fixes my issue.

Hope this helps other people having the same problem... Thanks Maxim!
