> 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 region is created. The meter(s) are removed when the region is destroyed/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 with time statistics enabled
> 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 with time statistics enabled
> 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 hits with time stats disabled*
> Given a cluster with a Server1 and a Locator1 with time statistics disabled
> When a java client issues a get operation using the region.get(key) command where the key exists
> Then a meter on Server1 exists such that:
> - Meter Name = 'geode.cache.gets'
> - Count = 1
> - Total Time = 0
> - Tag: region = region that the 'get' method was called against
> - Tag: result=hit
> *Scenario: Java client error response*
> Given a cluster with a Server1
> And a RegionA exists with NO entry with a Key="1"
> And the client is unauthorized for Key="1"
> 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
