FlowCacheStatistics

Provides the following statistics for flow cache since the time the edge dataplane is UP:

Number of active entries.
Number of cache entry insertions.
Number of bucket collisions when the entry insertion happens to a bucket which is full.
Number of key collisions when the entry to be inserted has a key colliding with that of an existing entry.
Number of cache hits, hit_rate, misses and skips.
Number of packets that cannot be cached.
Number of maximum entries with respect to size.

}

string

active

Optional

The number of current active entries in the flow cache.

string

bucket_collisions

Optional

The total number of times when during an entry insertion, the corresponding bucket is full with unexpired entries. This collision will result in a flow cache miss. This is valid only for mega flow cache. The counts are from the time the edge dataplane is UP and will be reset on edge reboot or edge dataplane restart.

string

dont_cache

Optional

The total number of packets that cannot be cached. The counts are from the time the edge dataplane is UP and will be reset on edge reboot or edge dataplane restart.

string

hit_rate

Optional

The rate at which the packets matching the flow cache are forwarded. The counts are from the time the edge dataplane is UP and will be reset on edge reboot or edge dataplane restart.

string

hits

Optional

The total number of packets forwarded due to matching flow cache entry. The counts are from the time the edge dataplane is UP and will be reset on edge reboot or edge dataplane restart.

string

insertions

Optional

The total number of times a new flow cache entry is added. The counts are from the time the edge dataplane is UP and will be reset on edge reboot or edge dataplane restart.

string

key_collisions

Optional

The total number of times a newly inserted entry has a key colliding with that of an existing entry. In this case, the new entry will replace the existing entry. This is only valid for mega flow cache. The counts are from the time the edge dataplane is UP and will be reset on edge reboot or edge dataplane restart.

string

max_seen_percentage

Optional

The percentage of maximum entries in a flow cache with respect to total size. This is collected from the time the edge dataplane is UP and will be reset on edge reboot or edge dataplane restart.

string

misses

Optional

The total number of packets passed on to the next layer due to cache miss. The next layer can be either slow path (in case of megaflow cache) or megaflow cache (in case of microflow cache). The counts are from the time the edge dataplane is UP and will be reset on edge reboot or edge dataplane restart.

string

skipped

Optional

The total number of packet misses due to unsupported packet type or the cache is disabled. The counts are from the time the edge dataplane is UP and will be reset on edge reboot or edge dataplane restart.
