Is there a way to prevent a custom variable from being truncated when entered in Nagios XI?

We have a Webhook URI that we're storing with a contact as "_WEBHOOKURL" and it appears that when it is entered in Nagios XI, it is just long enough that the last 6 characters of it are being truncated when stored.

Is this a problem with the UI? Is there a way to bypass this to properly store the URI?

basically, it's something like

http://example.outlook.com/<LONG UUID>

and Nagios is storing it as

http://example.outlook.com<LONG UUID missing the last 6 characters>

Hi @tgaastra,

From the UI the custom variable gets stored in the database, the default size for the variable value field there is 1024. How big is this URL?

Nagios XI uses the Nagios Core custom contact variables (_CUSTOMVARIABLES) which have a character limit of 256 characters by default. Any variable exceeding this length will be silently truncated when stored in the database. Football Bros

Thanks @danisa for that correction, I was looking at the wrong database (nagios vs nagiosql).

@tgaastra you can increase the size of that field. Please see this post for instructions: viewtopic.php?t=35053
