WalkthroughThe recent updates introduce enhanced functionality for handling proxy service configurations, command-related statistics, and logging. Notably, new methods for retrieving command statistics and setting logging thresholds were added. Additionally, new API endpoints and metrics configurations were introduced to support these functionalities, along with necessary structural changes to the codebase. Changes

Refactor getOpStats to reduce complexity and improve readability.
The getOpStats function is complex and mixes locking logic with operational logic. Consider separating these concerns for clarity.
- cmdstats.opmapLock.Lock()
- defer cmdstats.opmapLock.Unlock()
- stat, ok = cmdstats.opmap[opstr]
- if ok && stat != nil {
- return stat
- }
- stat = &opStats{opstr: opstr}
- for i := 0; i < IntervalNum; i++ {
- stat.delayInfo[i] = &delayInfo{interval: IntervalMark[i]}
- }
- s.stats.opmap[opstr] = stat
+ return createOpStats(opstr)This change proposes extracting the creation logic into a separate function, createOpStats, which would handle the instantiation and initialization of opStats objects.

Ensure proper error handling for StatsSetLogSlowerThan.
The function StatsSetLogSlowerThan is called without checking if the configuration value p.config.SlowlogLogSlowerThan is valid. It's important to ensure that this value is non-negative before setting it, as negative values could lead to unexpected behavior.
Consider adding a validation step before this function call:

StatsSetLogSlowerThan(p.config.SlowlogLogSlowerThan)
+ }Committable suggestion

Review the new CmdInfo struct for potential data encapsulation improvements.
The CmdInfo struct is directly exposing its fields which might lead to unintentional modifications from outside the package. Consider using getter methods to provide controlled access to these fields.
Proposed change:

Optimize the CmdInfo method to reduce redundant data fetching.
The CmdInfo method fetches operation statistics multiple times which can be optimized by reducing the number of calls to GetOpStatsByInterval.
Consider refactoring to fetch all required data in a single call:
func (s *Proxy) CmdInfo(interval int64) *CmdInfo {
info := &CmdInfo{
- Total: OpTotal(),
- Fails: OpFails(),
- QPS: OpQPS(),
- Cmd: GetOpStatsByInterval(interval),
+ stats: GetOpStats(interval), // Assume GetOpStats returns all necessary data in one call
}
- info.Redis.Errors = OpRedisErrors()
+ info.Redis.Errors = info.stats.RedisErrors
return info
}Committable suggestion was skipped due to low confidence.

Add error handling for negative values in StatsSetLogSlowerThan.
The function StatsSetLogSlowerThan does not handle negative values appropriately. It simply returns without setting the value or notifying the caller of the invalid input.
Proposed improvement:
func StatsSetLogSlowerThan(ms int64) {
if ms < 0 {
+ log.Errorf("Invalid value for log slower than: %d", ms)
return
}
cmdstats.logSlowerThan.Set(ms)

The getOpStats function is used to retrieve or create operation statistics. The locking mechanism is correctly implemented, but the function could be simplified to improve readability and reduce redundancy.
- cmdstats.opmapLock.Lock()
- defer cmdstats.opmapLock.Unlock()
- stat, ok = cmdstats.opmap[opstr]
- if ok && stat != nil {
- return stat
- }
- stat = &opStats{opstr: opstr}
- for i := 0; i < IntervalNum; i++ {
- stat.delayInfo[i] = &delayInfo{interval: IntervalMark[i]}
- }
- s.stats.opmap[opstr] = stat
+ return createOpStats(opstr)This change proposes extracting the creation logic into a separate function, createOpStats, which would handle the instantiation and initialization of opStats objects.
