Hi all,

You can use the below script which can be also be configured to send an email alert if the sybase tempdb free data or log space falls below 10% . i.e., tempdb
monitoring script.

select
"Data Size," = str(sum(size * abs(sign(segmap - 4))) / 512.0, 7, 2)+',',
"Data Used," = str(sum((size - curunreservedpgs(dbid, lstart, unreservedpgs)) * abs(sign(segmap - 4))) / 512.0, 7, 2)+',',
"Data Free," = str(100.0 * sum((curunreservedpgs(dbid, lstart,unreservedpgs)) * abs(sign(segmap - 4))) / sum(size * abs(sign(segmap- 4))), 3) + "%"+',',
"Log Size," = str(sum(size * (1 - abs(sign(segmap - 4)))) / 512.0, 7, 2)+',',
"Log Used," = str(sum((size - curunreservedpgs(dbid, lstart, unreservedpgs))* (1 - abs(sign(segmap - 4)))) / 512.0, 7, 2)+',',
"Log Free" = str(100.0 * sum((curunreservedpgs(dbid, lstart,unreservedpgs))* (1 - abs(sign(segmap - 4)))) / sum(size * (1 - abs(sign(segmap - 4)))), 3) + "%"

where segmap < 5
and dbid=2


you have to use conditional shell commands to check if the Log/Data free < threshold.
