Show calculated value in trigger name

[alexanders77]

Hello

I created a trigger, which fires if the memory usage of our redis goes above a certain threshold (80%), like so with the following expression in a template:

({Template App Redis:redis.cli.info[6379,used_memory].last()} / {Template App Redis:redis.cli.config.get[6379,{$CONFIG_COMMAND_NAME},maxmemory,2].last()}) * 100 > {$REDIS_MEMORY_USAGE}

{$REDIS_MEMORY_USAGE} is a template macro with the value of 80.

To get a better overview on places like the tr_status.php page and also in messaging, I'd like the trigger name to contain the calculated value (-> ({Template App Redis:redis.cli.info[6379,used_memory].last()} / {Template App Redis:redis.cli.config.get[6379,{$CONFIG_COMMAND_NAME},maxmemory,2].last()}) * 100), so that I can VERY quickly see, how severe the issue and actually what value the calc. returned.

How can I do that?

Thanks,
Alexander

Hello,

You can create this calculated item and after that put it in your trigger as a second expression something like: and calculated_item_key.last()>0 (I hope this value will always be above 0). After that put this in your trigger name: Used Memory is {ITEM.LASTVALUE2}

Thanks a lot, this worked well.
