Ok. thx, Issue resolved.
Thx for the help kedar, we have our own alerting system, we are implementing this to monitor error , logs position & start / stop slave things handy, rather than giving server access to users.
I tried to install this script on our server but file , position , IO run , sql run , error number & error message fields are getting blank. i have mysql version 5.6.26 on centos .
Can you please help me to solve this ?
Sure Siddharth,
You need to make sure your credentials are correct and in place. You need to change following:
#host-name & ports for replication servers
$slave = “localhost”; # Provide IP / FQDN
$master = “localhost”;# Provide IP / FQDN
$slaveport=3306; # If both mysql are on different node then port should be default 3306 for both masters.
$masterport=3307;
#considered a common username password for accessing both servers#
$username=”user”;
$password=”xx”;
>> Make sure these credentials above works. Say you’re having the script on remote machine then you should be able to connect to both masters using this credentials.
Let me know.
Hi kedar,
Can i monitor master master replication with this script ?
Hi Siddharth,
This has been pretty old script and things have evolved. What’s importantly missing here is alert mechanism. You do not get alerted for any issues found unless you view the page.
If you want to use this, you better add a function to send-out email/msg.
That said, this only is limited to replication; there are other monitoring tool which monitors much more than just replication status and that is desired. Nagios with Percona monitoring plugins is one way to implement.
Hope this helps,
Kedar.
