Check MK monitoring Oracle

1. Install the new Check_mk_agent,1.2.5i7 version above and make sure the Mk_oracle script is installed

Copy the mk_oracle script from the server side to the target server

cp /usr/share/check-mk-agent/plugins/mk_oracle /usr/lib/check_mk_agent/plugins/ls -lth /usr/lib/check_mk_agent/plugins/mk_oracle

2, the database to CHECK_MK user empowerment:
(1) Grant Select_catalog_role to CHECK_MK

[email protected]# su - oracle[email protected]:~> export ORACLE_SID=<SID of an Instance>[email protected]:~> sqlplus / as sysdbasqlplus> create user check_mk identified by secret_password;sqlplus> grant select_catalog_role to check_mk;sqlplus> connect check_mk/secret_passwordsqlplus> exit[email protected]:~> export ORACLE_SID=<SID of an Instance>

(2) ASM-related

[email protected]# su - oracle[email protected]:~> ps ax | grep pmon | grep ASM[email protected]:~> export ORACLE_SID=+ASM1[email protected]:~> sqlplus / as sysasmsqlplus> create user check_mk identified by secret_password;sqlplus> grant sysdba to check_mk;sqlplus> exit

3. Modify the/etc/check_mk/sqlplus.sh file
vi /etc/check_mk/sqlplus.sh
Modified to:

ORACLE_SID=$1if [ -z "$ORACLE_SID" ] ; then    echo "Usage: $0 ORACLE_SID" >&2    exit 1fisu - oracle -c "ORACLE_SID=$ORACLE_SIDORAENV_ASK=NOsource /home/oracle/.bash_profilesqlplus -s check_mk/password"

4. Edit the/etc/check_mk/mk_oracle.cfg file
vi /etc/check_mk/mk_oracle.cfg
Add to:

#ASMUSER=check_mk:password:sysdba:hostname:port#DBUSER=check_mk:password:sysdba:hostname:portASMUSER=check_mk:passwordDBUSER=check_mk:password

Copy TNS file to/ETC/CHECK_MK
cp /u01/app/oracle/11.2.0/dbhome_1/network/admin/tnsnames.ora /etc/check_mk/

5. Edit/etc/check_mk/sqlnet.ora

vi /etc/check_mk/sqlnet.oraLOG_DIRECTORY_CLIENT = /var/log/check_mk/oracle_clientDIAG_ADR_ENABLED = OFFSQLNET.WALLET_OVERRIDE = FALSEWALLET_LOCATION = (SOURCE=  (METHOD = FILE)  (METHOD_DATA = (DIRECTORY=/etc/check_mk/oracle_wallet)) )

6. Execute the Verification statement:

export MK_CONFDIR="/etc/check_mk";/usr/lib/check_mk_agent/plugins/mk_oracle -texport MK_CONFDIR="/etc/check-mk-agent";/usr/share/check-mk-agent/plugins/mk_oracle -t

Output:
[Email protected] check_mk]#export MK_CONFDIR="/etc/check_mk";/usr/lib/check_mk_agent/plugins/mk_oracle -t
