Wildcard characters in trigger conditions

Hi,

I am currently creating an advanced custom node poller alert. I have used the universal device poller to poll the hardware status of our servers and the results are returned in a table. The status returned is a text value. So, for example, a server might have 8 fans and so the table will contain 8 rows (1 for each fan status). Below is an example of the status text retrieved for 4 fans.

Fan Sensor 1 reports normal.

Fan Sensor 2 reports normal.

Fan Sensor 3 reports normal.

Fan Sensor 4 reports normal.

What I need is for the condition to be true when the one of the fan sensors does not report normal. Does anyone know if there is a way to use wildcards in a trigger condition? For example:

field Status is not equal to Fan Sensor * reports normal.

I thought about creating a condition for each fan but different model servers (and even the same model with a different configuration) have different numbers of fans. Any idea's at all would be really appreciated.

Cheers,

I have not tested whether wildcards can be used in the text string in that way, but I am guessing that you already have using * or %, hence the question.

As there is not a 'Does not Contain', simply reverse it. In the 'Trigger alert when' use a reverse condition such as 'None' and then in the filter:

field status contains normal

Let me know how you get on, as i would be interested in the outcome

Sorry for the delay in replying to this post. I have reversed the condition as you suggested and it seems to be working fine.

Thanks,

I have this issue too. I am trying to filter on "C-NE AP" and the white space is causing an issue

Using reverse logic still will not read the space in my interface caption. I've been told this is actually a bug and you guys are working on it.

Probably want to post your own question rather than commenting on a 9 year old thread.

I'm not quite sure what you mean it will not read the space in your caption... do you mean you are trying to do a mid string wild card? I can imagine that the GUI wouldn't let you just drop a */%/_ inside the string but you could probably achieve a similar result by getting creative with using combinations of starts with, contains, ends with conditions.

If you need to be extremely explicit in how the name is formatted you might have to resort to using a custom SQL condition, since SQL has fairly powerful string parsing capabilities.
