Virtual cache represent the cache nodes detected by server agents' plugins. The performance metrics of the cache are also from the Cache client-side perspective.
For example, Redis plugins in the Java agent could detect the latency of command As a result, SkyWalking would show traffic, latency, success rate, and sampled slow operations(write/read) powered by backend analysis capabilities in this dashboard.
The cache operation span should have
cache.type
, value = The type of cache system , e.g. rediscache.op
, value = read
or write
, indicates the value of tag cache.cmd
is used for write
or read
operationcache.cmd
, value = the cache command , e.g. get,set,delcache.key
, value = the cache keyRef slow cache doc to know more slow Cache commands settings.
