Help in avoiding hitting the new storage limit

[dgoldm]

After upgrading to 2025.1 I was blocked from viewing events because I was way over the new storage limit for the indivual license.
I somehow managed to blindly modify the retention policies to trim down the used space to a permitted value.

I have a few questions about how to avoid such issues in the future (btw, we're planning to upgrade to the also limited Team license in the near future).

1. How do I determine the current used space? Is it the sum of the sizes listed in the Statistics card on the Storage page?
2. Is it possible to be alerted when it reaches a certain threshold?
3. Can I determine how much space is taken up by a subset of events, such as a certain signal or a certain API key?

Hi @dgoldm,

On Data > Storage, indexes themselves aren't included, but the other four categories (indexed bytes, unindexed bytes, queued for reindexing, and buffered bytes) are.

To set an alert, go to Settings > General, and set a system notification target app instance. An alert is generated within 10% or so of the limit.

There's no completely accurate way to measure space for a subset of events, but using sum(Length(ToJson(@Data))) over them is a reasonable (but slow) approximation.

Hope this helps,
Nick
