Using the transaction sensor



Hi Using a transaction sensor, i would like the sensor to fail if a certain sentence is in the source. So i write

  • An error has happened*

in the "response must not include" field. However, when I have more tahn one word in this field, the sensor responds with OK. If I write

  • happened* the sensor fails.

So how should I do this?

Dear Lars,

please be aware that this check is case sensitive. So 'happened' and 'Happened' are not the same. Furthermore, * as wildcards might not work, please try it without them (or try ? as wildcard).

Best regards.

Thanks for the response. I have tried every combination of case and with/without stars. Even in this simple setup I'm nott getting a "hit" String starting at byte 2344 in source code:"Der er desværre sket en fejl" Der = ok er = Error: String found [er] r = Error: String found [r] sket = ok

*sket* = ok
*ske* = ok

Seems like the strings found are from other parts of the source.

But when I'm checkin for strings earlier in the source (within the first 200 bytes) all my matches work as expected.

I have set a limit download of 0 (default value), and I assume that this is unlimited, but it seems that this could have an effect. Even when setting this to 5 (the source is 3 Kb) I'm not getting my match.

Are you able to elaborate on this?

Dear Lars,

we've just tried it with a few websites, there is no limitation which part of the HTML-source is checked (please be aware that only HTML is checked, Javascript is not parsed). '0' in the download limit means indeed unlimited download for the sensor. As already said, * do not work as wildcards. Please do not use them.

Best Regards.
