Update problem message (ITEM.VALUE) when the value changes

[okelet]

When a trigger is triggered, and a problem is generated, where the message contains a value from the expression, the value in the message is not updated with the real value of the item. Is there any way to achieve this?

For example, when monitoring a datasource, I have a trigger when datasources in use is more than 80%, so a problem is generated with 81% in the message; but if in the next check, the new value of the item has changed, for example, to 85%, the message of the problem is the same than before (81%). The same happens, for example, when monitoring the disk space.

Note: I don't want to use the "Multiple PROBLEM event generation mode", as this would generate lots of problems, where each problem should be ACKed manually.

Item.lastvalue?

[okelet]

No, because ITEM refers to the item in the trigger expression, but the expression doesn't contain the "status" item.

I agree, ITEM.LASTVALUE.

For example, let's say I have a trigger set up like this:

Name: File size > 64 ({ITEM.VALUE}, {ITEM.LASTVALUE})
Expression: {myhost:vfs.file.size[/tmp/foo].last()}>64

If I create a 75 byte file called /tmp/foo, an event gets generated with the description "File size > 64 (75 B, 75 B)". However, if the file continues to grow to 128 B, then the after the next check, the event name changes to "File size > 64 (75 B, 128 B)".

So, ITEM.VALUE does not get updated, but ITEM.LASTVALUE does.

Hi, i now its long time
i face the same issue, i want in the dashboard where i get the alert to see
the latest value the system recivet from the agent, but it print me only the first value

{ITEM.LASTVALUE1},{ITEM.VALUE1},{ITEM.LASTVALUE})
all the values are the same value
