While using this dbi block
<Plugin dbi>
<Query "teste_query">
Statement "select sum(total_logical_reads) as log_reads
from sys.dm_exec_query_stats"
<Result>
Type "gauge"
ValuesFrom "log_reads"
</Result>
</Query>
<Database "MSSQLServer">
Driver "freetds"

DriverOption "username" "SA"
DriverOption "password" "Paxazx01"
Query "teste_query"
</Database>
</Plugin>
The problem is with things like this `sum(something) as this' I just
can't get it working.. The query works fine on SSMS and retruns only one
line and one column, Any idea?
PS: I'm trying to monitor the reads/writes and worker time on MS
SQLServer..
Regards,
I track the problem...
This message
'dbi plugin: Column `log_reads': Don't know how to handle source type 4'
Comes from here [1]. Seems that libdbi is returning something unexpected
by dbi plugin.
The type for stands for DBI_TYPE_BINARY here [2] line 114
[1] https://github.com/collectd/collectd/blob/master/src/dbi.c#L132
[2]
http://libdbi.cvs.sourceforge.net/viewvc/libdbi/libdbi/include/dbi/dbi.h.in?revision=1.13&view=markup
line 114
So, I think, SUM() would return integer types, but for libdbi, don't,
I'm digging deeper on this..
