Hello,
I have the following table setup:
ID hostname facility priority date message
ID is auto incrementing.
This is used to store all of the syslog messages, currently there are over 7 million:
The following query takes forever:
Select machine,count(*) from syslog WHERE date1 > (NOW() - INTERVAL 24 hour) AND message LIKE 'sshd%' GROUP BY machine;
I have created the following indexs but when I use Explain it says that the query has to search all the rows:
datehostfacility 1 date1 A 352489 datehostfacility 2 machine A 1409956 datehostfacility 3 facility A 1409956
datemesghost 1 date1 A 640889 datemesghost 2 message(15) A 7049783 datemesghost 3 machine A 7049783 datemesghost 4 facility A 7049783 datemesghost 5 priority A 7049783
What would the proper index be ?
Michael
