  • Trouble with Mongodb & Cacti Monitor Plugins

    Love your work!

    After downloading the plugins for cacti I got right to monitoring my Mysql DB. And life is good.
    So I tried the Redis tools, and after a quick adjustment in the ss_get_by_ssh.php graphing of Redis springs to life. Great!
    So Mongo is next. Same ssl, keys, no changes to the cacti env. It looks good so far... but data never populates. :-(

    manually run the php from the cacti host as described in the documents; php /usr/share/.../ss_get_by_ssh.php --type mongodb --host my-host --items mk,ml

    Result returned is mk:-1 ml:0
    I get this result if run as root or cacti. Since this was similar to my Redis deployment, I figured ssh was the issue. After manually ssh'ing into the mongo server, running the query, I get plenty of results. Yet I'm still get a -1 return from the cacti host. I try this on all the --items for mongo... and ~75% return -1 while the rest return 0

    I'm new to Percona and only just relearning Cacti.
    Anyone able to help me out?

      I don't understand why this is not working.
      from the mongo db host I see the valid ssh connections
      Jul 23 17:47:20 <mongo-host> sshd[3872]: Accepted publickey for root from <cacti-host> port 55998 ssh2
      Jul 23 17:47:21 <mongo-host> sshd[3872]: Received disconnect from <cacti-host>: 11: disconnected by user

      On the cacti-host, in /tmp/<mongo-host>_mongodb_cacti_stats.txt I can see the temp file for the stats. contain this;

      If I ssh manually with the same user and ssh key I use in the ss_get_by_ssh.php, into the mongo-host and run the command below I get complete success. I'm thinking a path issues?
      db._adminCommand({serverStatus : 1});

          I am having the same issue listed here. ss_get_by_ssh.php works great to my other monitors. It is collecting CPU, memory, networking, etc from my mongoDB server. It just wont pull the mongoDB status.

          I do have authentication in place for my mongoDB and I am guessing thats the issue but have not been able to find any documentation on where to configure that.

          I am running Percoan Monitoring Tools 1.1.3, i am not opposed to installing 1.1.5 the latest at this time but I was hoping for some direction to go in before that.

            Same issue here with authentication being the likely culprit - anybody here resolve this?
