How to get show distribution time_to_live

[Cookiery]

Hi team, I want to get the time_to_live. I can get the data from asadm -e 'show distribution time_to_live'. But it returned the table format data. I want to get JSON format data from golang SDK.

Thank you very much!

Hi @Cookiery ,

You can get the ttl distribution through the go client using info commands, then parse that to JSON. The info command you want is histogram. Specifically something like this to get the ttl histogram. histogram:namespace=<namespace_name>;type=ttl

Go client example...

package main

import (
        "log"
        "time"

        as "github.com/aerospike/aerospike-client-go/v6"
)

func main() {
        // remove timestamps from log messages
        log.SetFlags(0)

        // connect to the host
        cp := as.NewClientPolicy()
        cp.Timeout = 10 * time.Second

        // cp.User = "admin"
        // cp.Password = "admin"

        conn, err := as.NewConnection(cp, as.NewHost("localhost", 3000))
        if err != nil {
                log.Fatalln(err.Error())
        }

        // Login if needed
        // if err := conn.Login(cp); err != nil {
        //      log.Fatalln(err.Error())
        // }

        infoMap, err := conn.RequestInfo("histogram:namespace=test;type=ttl")
        if err != nil {
                log.Fatalln(err.Error())
        }

        cnt := 1
        for k, v := range infoMap {
                log.Printf("%d :  %s\n     %s\n", cnt, k, v)
                cnt++
        }
}

output:

% go run main.go
1 :  histogram:namespace=test;type=ttl
     units=seconds:hist-width=2095700:bucket-width=20957:buckets=0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,39597
