Hi Adrien, There's no single answer to your question. Most, if not all of these parameter depends on your load and use case. zk_open_file_descriptor_count is not a percentage, but you can easily do by using the max count also.
There's hardly a best value to be used for all use cases. For example zk_open_file_descriptor_count you could check if it's starting to grow rapidly, or go over a certain threshold as you mentioned. Or zk_pending_syncs - are there any bursts in your use case? How many clients are there? How many requests on high load? What might be an alert level for one use case can be perfectly normal load in another. zk_fsync_threshold_exceed_count might not be the best monitoring parameter. This is more to be used once you detect something is wrong, to check if it's been going on for a while. But it is better to look for fsync warnings in the log. At least I would look for that. Again, what's the use case? Regards, Norbert On Fri, Apr 5, 2019 at 11:33 PM Muhammad Gelbana <[email protected]> wrote: > Yes. Suprisingly it isn't.
