SQL monitoring
We have MYSQL in production, and want have something like monitor or feedback on SQL status.
In MSSQL, we can do lot thing
Example : Monitor blocking, long query, job status
Google and find
1. mtop :
mytop is a console-based (non-gui) tool for monitoring the threads and overall performance of a MySQL 3.22.x, 3.23.x, and 4.x server.
more information
2. Find this script:
#!/bin/sh
# Variables
DBUSER=someone
DBPASS=something
SECONDS=15
# Main loop
while true
do
mysqladmin -u$DBUSER -p$DBPASS processlist |
egrep -vw 'Sleep|processlist|Binlog Dump' |
awk -F'|' '{print $6, $7, $8, $9}'
# First line of vmstat is historical, so take the second
vmstat 1 2 | tail -1
# Sleep for a while
sleep $SECONDS
done
3. MYSQLReport
mysqlreport makes a friendly report of important MySQL status values. mysqlreport transforms the values from SHOW STATUS into an easy-to-read report that provides an in-depth understanding of how well MySQL is running. mysqlreport is a better alternative (and practically the only alternative) to manually interpreting SHOW STATUS.
Anything else?
