Oracle cx_Oracle python nagios DB check

I used this python plugin for nagios to find delay in a database. Database is used for etl processes. You need to create a readonly user at Oracle DB.

It takes arguments ip of db, delay , table name holds delay data, and sid

#!/usr/bin/python
import sys,os


import cx_Oracle
ip = str(sys.argv[1])
port = 1521
SID = str(sys.argv[4])
maxcount = sys.argv[2]
TABLE = str(sys.argv[3])

dsn_tns = cx_Oracle.makedsn(ip, port, SID)
connection = cx_Oracle.connect('dbuser', 'dbpass', dsn_tns)
cursor = connection.cursor()
cursor.execute("SELECT max(m5_id) FROM  " + TABLE )

m5_id = cursor.fetchall()[0][0]
cursor.execute("SELECT ROUND((SYSDATE -(SELECT MAX(M5_REAL_DATE_LOCAL) FROM " + TABLE + "))*1440,2)  FROM DUAL")
delay = cursor.fetchall()[0][0]
cursor.close()
connection.close()


if int(delay) < int(maxcount):
        print "OK | "  + str(delay) 
        sys.exit(0)
else:
        print "NOK | "  + str(delay) 
        sys.exit(2)
