Redis memory analysis
======
🔎 Analyzing memory of redis is to find the keys(prefix) which used a lot of memory, export the analysis result into csv file.

## Binary File Usage
1. Download the appropriate binary file from [Releases](https://github.com/hhxsv5/go-redis-memory-analysis/releases)
2. Run
```Shell
# help
./redis-memory-analysis-linux-amd64 -h
Usage of ./redis-memory-analysis-darwin-amd64:
-ip string
The host of redis (default "127.0.0.1")
-password string
The password of redis (default "")
-port uint
The port of redis (default 6379)
-rdb string
The rdb file of redis (default "")
-prefixes string
The prefixes list of redis key, be split by '//', special pattern characters need to escape by '\' (default "#//:")
-reportPath string
The csv file path of analysis result (default "./reports")
# run by connecting to redis
./redis-memory-analysis-linux-amd64 -ip="127.0.0.1" -port=6380 -password="abc" -prefixes="#//:"
# run by redis rdb file
./redis-memory-analysis-linux-amd64 -rdb="./6379_dump.rdb" -prefixes="#//:"
```
## Source Code Usage
1. Install
```Shell
//cd your-root-folder-of-project
// dep init
dep ensure -add github.com/hhxsv5/go-redis-memory-analysis@~2.0.0
```
2. Run
- Analyze keys by connecting to redis directly.
```Go
analysis := NewAnalysis()
//Open redis: 127.0.0.1:6379 without password
err := analysis.Open("127.0.0.1", 6379, "")
defer analysis.Close()
if err != nil {
fmt.Println("something wrong:", err)
return
}
//Scan the keys which can be split by '#' ':'
//Special pattern characters need to escape by '\'
analysis.Start([]string{"#", ":"})
//Find the csv file in default target folder: ./reports
//CSV file name format: redis-analysis-{host:port}-{db}.csv
//The keys order by count desc
err = analysis.SaveReports("./reports")
if err == nil {
fmt.Println("done")
} else {
fmt.Println("error:", err)
}
```
- Analyze keys by redis `RDB` file, but cannot work out the size of key.
```Go
analysis := NewAnalysis()
//Open redis rdb file: ./6379_dump.rdb
err := analysis.OpenRDB("./6379_dump.rdb")
defer analysis.CloseRDB()
if err != nil {
fmt.Println("something wrong:", err)
return
}
//Scan the keys which can be split by '#' ':'
//Special pattern characters need to escape by '\'
analysis.StartRDB([]string{"#", ":"})
//Find the csv file in default target folder: ./reports
//CSV file name format: redis-analysis-{host:port}-{db}.csv
//The keys order by count desc
err = analysis.SaveReports("./reports")
if err == nil {
fmt.Println("done")
} else {
fmt.Println("error:", err)
}
```
