Strange behavior of {{HOSTNAME}:{TRIGGER.KEY}.last(0)}

[Umair]

I have defined an ITEM which is returning a string that is too long to be contained in CHARACTER.

So, i am using TEXT to store the string returned.
The LATEST DATA shows the complete string which is returned form the Agent.


PROBLEM :

When i write the following command in ACTION to send an email.

{{HOSTNAME}:{TRIGGER.KEY}.last(0)}

It returns only the first line of the String.
Strange...!!

I tried changing the ITEM return value to LOG, so that it could support more text.

Now, when the email was sent, it showed me an incomplete part of the string...
only the first 4 lines....
It did not show me the complete string.

Any cluses as how i can get the full string returned by the ITEM in the Email Body ?

In Reference to the command (which i am using in ACTION as a content of my email):

{{HOSTNAME}:{TRIGGER.KEY}.last(0)}

with last(0) :

I did some research of my own and found that this command returns a fixed string of length 255 characters. (i only used it in the email body)
Is this some sort of an implication or a bug ?

Our scenario involves reporting back the exceptions which would have been raised if a process dies.
If i am getting some response from a code, i would definitely want to see the whole message in the email instead of the defined 255 characters.

Is this a Bug ???

I would call it a limitation not a bug

awwww...

Umm, dont you think this limitation is kind of a drawback ?
Like in our sceanrio, we can do nothing except trim down our exceptions.

can it be changed ??
i mean by changing the DB Field's size ?? (If that is the only thing which requires change).

Yes, I do think so! It will be addressed in one of future releases.

Alexei, Has this problem also been solved in 1.4.1 ??

[Alexei]

No, it wasn't.

very easy fix, im surprised a dev hasn't mentioned it.

change the field type of "lastvalue" & "prevvalue" in zabbix.items from varchar(255) to Text.

didn't work for me. however, I made a patch for src/libs/zbxserver/evalfunc.c.
