RecentReadLatency metrics has been deprecated for years (1.1 or 1.2) and were 
removed in 2.2. It was a very misleading metric. Instead pull from the Table's 
ReadLatency metrics from the org.apache.cassandra.metrics domain.

Read-/ Write Latency - Cassandra 2.1 .15 vs 3.10

[Anumod Mullachery]

Hi,

We were running splunk  queries to pull read / write latency.

It's working fine in 2.1.15 , but not returning result from upgraded
version 3.10.

The bean used in the script is as shown below.

Let me know, if any changes on the functionality on 2.1.15 vs 3.10 or
it replaced to some other bean.


perf_queries= {
   "org.apache.cassandra.db:type=StorageProxy" =>
"RecentReadLatencyMicros,RecentWriteLatencyMicros",
}

stage_queries= {
   "org.apache.cassandra.request:type=*" =>
"ActiveCount,PendingTasks,CurrentlyBlockedTasks",
}

curl 
http://localhost:8778/jolokia/read/org.apache.cassandra.db:type=StorageProxy/RecentReadLatencyMicros,RecentWriteLatencyMicros

curl 
http://localhost:8778/jolokia/read/org.apache.cassandra.request:type=*/ActiveCount,PendingTasks,CurrentlyBlockedTasks

Read-/ Write Latency - Cassandra 2.1 .15 vs 3.10

[Mullachery, Anumod (Contractor)]

Hi,

We were running splunk  queries to pull read / write latency.

It's working fine in 2.1.15 , but not returning result from upgraded version 
3.10.

The bean used in the script is as shown below.

Let me know, if any changes on the functionality on 2.1.15 vs 3.10 or it 
replaced to some other bean.


perf_queries= {
   "org.apache.cassandra.db:type=StorageProxy" => 
"RecentReadLatencyMicros,RecentWriteLatencyMicros",
}

stage_queries= {
   "org.apache.cassandra.request:type=*" => 
"ActiveCount,PendingTasks,CurrentlyBlockedTasks",
}

curl 
http://localhost:8778/jolokia/read/org.apache.cassandra.db:type=StorageProxy/RecentReadLatencyMicros,RecentWriteLatencyMicros

curl 
http://localhost:8778/jolokia/read/org.apache.cassandra.request:type=*/ActiveCount,PendingTasks,CurrentlyBlockedTasks
