| # Perf | ||
|
|
||
| Perf is a performance test module that is scheduled to run and cache those tests results in redis which can be retrieved later over RMB call. | ||
|
|
||
| Perf tests are monitored by `noded` service from zos modules. | ||
|
|
||
| ### Usage Example | ||
|
|
||
| 1. Create a task that implement `Task` interface | ||
|
|
||
| ```go | ||
| type LoggingTask struct { | ||
| TaskID string | ||
| Schedule string // should be in cron syntax with seconds ("* 0 * * * *") | ||
| } | ||
|
|
||
| func (t *LoggingTask) ID() string { | ||
| return t.TaskID | ||
| } | ||
|
|
||
| func (t *LoggingTask) Cron() string { | ||
| return t.Schedule | ||
| } | ||
|
|
||
| // a simple task that returns a string with the current time | ||
| func (t *LoggingTask) Run(ctx context.Context) (interface{}, error) { | ||
| result := fmt.Sprintf("time is: %v", time.Now()) | ||
| return result, nil | ||
| } | ||
| ``` | ||
|
|
||
| 2. Add the created task to scheduler | ||
|
|
||
| ```go | ||
| perfMon.AddTask(&perf.LoggingTask{ | ||
| TaskID: "LoggingTask", | ||
| Schedule: "* 0 * * * *", // when minutes is 0 (aka: every hour) | ||
| }) | ||
| ``` |

There was a problem hiding this comment. Using the task name alone as a key is not a good idea. The same redis instance is used by other apps on the system to store and queue data. Hence you need to create some sort of a Having a prefix also makes it easier for range scan. For example if u wanna return ALL tests u can scan KEYS with |

There was a problem hiding this comment. As commented before, the GetCache is not correct. The performance framework internal details (how tests are run or how results are retrieved) is only an implementation details. The PerformanceMonitor struct then API should be In other words, why a user of this framework know that the result is cached for example |

There was a problem hiding this comment. This is not how u use the redis Pool. The idea of a Pool of connection that u Get a connection from the pool, use it and then close it immediately when you are done using it. Closing a connection will return the connection to the pool (the pool might not close the connection) but keep it alive for the next one to need a connection (by calling the pool.Get()) So what u are doing is breaking the pooling contract by hording a connection forever. This is also really bad because if the connection is interrupted (or lost because of any reason) there is NO way that u renew the connection. The pool on the other hand tests the connection before it give u one when u do a Get, and renew it if needed. In summary, what u need to do is to keep the pool on you structure (not a connection) and in you setCache and Get methods what u need to do is con := pm.pool.Get()
defer con.Clonse()
