Live Varnish and Memcached Stats Buttons in Server Management Services Tab
Every running Varnish or Memcached service listed in your server’s Services tab now carries a Stats button. One click opens a snapshot of how that cache is actually performing.
01 What the snapshot shows
The dialog reports the overall hit rate, how many requests were served straight from cache against how many were fetched from the backend, how many objects are stored, how much memory is in use, how many evictions have occurred, and more besides.
| Metric | What it tells you |
|---|---|
hit rate | The share of requests the cache answered on its own |
cache vs backend | Requests served from cache against those fetched from the backend |
objects stored | How much is currently held in the cache |
memory used | How much of the allocated memory the cache occupies |
evictions | Objects pushed out to make room, a sign the cache may be undersized |
02 Explanations in place
Each metric has an info icon. Hover it for a plain-English explanation of what the number means, so you do not need to keep Varnish or Memcached documentation open alongside. The dialog also shows exactly how long the counters have been running, which matters when you are judging whether a hit rate is representative or just freshly reset.
