Hi All,

The Tablespace usage of DB Server went to critical and unknown state
with Status Information as (Service check timed out after 480.03 seconds)
Suggest us What can be done?

Thanks and Regards,
Mayur

What is the full command that is being run for this check? What results do you get if you run it from the command line? Is there a problem with the remote host, database, or service?

----I waited for 5 min then i did CTRL+C and i got error

^CUNKNOWN - check_oracle_health timed out after 60 seconds

whereas same command for other tablespace check is working fine.

there are 3 service added for each database and 1 tablespace monitoring service is only giving error for 1 database only.
we haven't change anything earlier.

connection to database worked very well , only challenge is tablespace monitoring service.

LINKTEST READ WRITE

is it possible that the password you are using for the dbtestusr contains a special char that is being interpreted by the CLI such as a $ > | etc?

If so these would need to be properly escaped

1. in Nagios tablespace service was being monitored earlier with query :

--connect "(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=10.202.23.43)(PORT=1521)) (CONNECT_DATA=(SERVICE_NAME=linktest.lhc4net.lhc.com) (INSTANCE_NAME=linktest)))" --user dbtestusr --password dbtestpwd --mode tablespace-usage --warning 85 --critical 90

Which I changed with the following query, now database is connecting with SID instead of service name

--connect "(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=10.202.23.43)(PORT=1521)) (CONNECT_DATA=(SID=LINKTEST)))" --user dbtestusr --password dbtestpwd --mode tablespace-usage --warning 85 --critical 90

2. In both database (linktest and hoeghdb) , I have cleared database recyclebin object.

After apply configuration , both services are now OK and being monitored by Nagios.

Thanks for your help. please close the case.

Thanks
