After having updated most servers to Debian Squeeze (6.0), I noticed that the packaged mytop utility didn't work with the new mysql-server-5.1. After looking for a solution for a long time, I found out that the variable name for the number of queries has changed in 5.1 - from "Questions" to "Queries" (or maybe the other way round). Thus, a dirty solution is to apply the following patch to /usr/bin/mytop:
--- /usr/bin/mytop 2009-04-06 23:49:09.000000000 +0200
+++ mytop 2011-08-18 10:54:09.000000000 +0200
@@ -794,6 +794,11 @@
{
my $key = $ref->{Variable_name};
my $val = $ref->{Value};
+ if ($key eq 'Queries') {
+ $key = 'Questions';
+ } else { if ($key eq 'Questions') {
+ $key = 'Queries';
+ } }
$STATUS{$key} = $val;
}
This solved it for me. Of course, the correct solution would be to check the MySQL version and act accordingly, but I leave that as an exercise to the reader :)
