Aaron Lindsey updated GEODE-7326:
---------------------------------
Summary: Add cache gets timers (was: Add cache gets timer)
> Add cache gets timers
> ---------------------
>
> Key: GEODE-7326
> URL: https://issues.apache.org/jira/browse/GEODE-7326
> Project: Geode
> Issue Type: Improvement
> Reporter: Aaron Lindsey
> Priority: Major
>
> h3. Why
> Users want to understand the performance of their operations within the
> server.
> h3. Acceptance Criteria
> Type: timer
> Name: geode.cache.gets
> Tags: region, result=hit/miss
> Lifecycle of meter: The hit/miss meter for each region is created when the
> first GET on that user region happens. The meter(s) are only removed when the
> cache is closed.
> Description for meter: The total time and count for GET requests from clients.
> Thing to measure : A count and total time for GET operations that didn't
> error, by this specific Server (1 or many cacheservers) in the geode cluster
> from when the server receives the request to when it sends the response.
> Business Rule for this measurement: This meter records any operation sent
> through a CacheServer
> h3. Scenarios
> *Scenario: Java Client Hits*
> Given a cluster with a Server1 and a Locator1
> When the oldest supported java client issues 5 get operations using the
> region.get(key) command
> Then a meter on Server1 exists such that:
> - Meter Name = 'geode.cache.gets'
> - Count = 5
> - Total Time = total time spent from received request to response to client
> for these 5 requests
> - Tag: region = region that the 'get' method was called against
> - Tag: result=hit
> *Scenario: Java Client Misses*
> Given a cluster with a Server1 and a Locator1
> When the oldest supported java client issues 5 get operations where the user
> is getting a key that doesn't exist in the region using the region.get(key)
> command
> Then a meter on Server1 exists such that:
> - Meter Name = 'geode.cache.gets'
> - Count = 5
> - Total Time = total time spent from received request to response to client
> for these 5 requests
> - Tag: region = region that the 'get' method was called against
> - Tag: result=miss
> *Scenario: Java client error response*
> Given a cluster with a Server1
> And a RegionA exists with NO entry with a Key="1"
> And a CacheLoader that throws an exception when invoked
> When the client issues a region.get(1) request
> Then no meter on Server1 should exist like:
> - Meter Name = 'geode.cache.gets'
> - Tag: region = RegionA
