THOLD: Poller[0] ERROR: RPN Expression is invalid!

[antokapo]

Hi

I'm getting many messages in cacti log like this :

THOLD: Poller[0] ERROR: RPN Expression is invalid! THold:'xxx.xxx.xxx.xx - bps - TenGigE0/1/0/1 - TenGigE0/1/0/1 [traffic_out]', Value:'114442710.52159', Expression:'|ds:traffic_out|,8,*,|query_ifHighSpeed|,1000000,*,/,100,*'

and i'm wondering if there's something wrong in interface.xml file.

My enviroment :

Double check that RPN Expression, something doesn't look right about it.

Hi

I'm not very confident with RPN expressions, we started to use THOLD recently to alert on threshold reached by traffic on some router interfaces.

In which file is the RPN expression stored ?

thanks

Its not stored in a file, you need to edit the threshold, scroll down to where it says "RPN Expression" and fix it.

Hi

Yes, sure, i realized after your comment that settings page is on Cacti dashboard.

We use the same thold template also for other interfaces and no error arises, only for some interfaces i noticed the error message,
this sounds me strange

I checked the RNP expression and it's a valid expression, and it works for various interfaces that we monitor, so i don't think the problem is the correctness of the RPN expression.

Thanks

Maybe query_ifHighSpeed is missing from the Data Query or XML file, or for this interface, it returned a null value. The RPN looks good otherwise.

Ok, i can i check this ? i looked at the interfaces.xml file and it contains query_ifHighSpeed section ..

Please close this post, i resolved with manual update of thold_data table that had disaligned data on the graph_id anche graph_template columns for some thresholds.
