我可以使用 OPS$ 帐户通过 sqlplus 登录我的数据库，但似乎无法让它与 nagios check_oracle_health 配合使用。我正在从命令行进行测试。
nagios@servername:/usr/local/nagios/libexec$ sqlplus /@TESTDB

OPS$NAGIOS
使用用户名和密码登录确实可行，但我所在公司的政策不允许这样做。
nagios@servername:/usr/local/nagios/libexec$ ./check_oracle_health --connect=read/pw@TESTDB--mode=connection-time
OK - 0.22 seconds to connect as READ| connection_time=0.2174;1;5
nagios@omonopsview:/usr/local/nagios/libexec$ ./check_oracle_health --connect=/@TESTDB --mode=connection-time
CRITICAL - cannot connect to /***@TESTDB. ORA-12545: Connect failed because target host or object does not exist (DBD ERROR: OCIServerAttach)
nagios@servername:/usr/local/nagios/libexec$ ./check_oracle_health --connect=TESTDB --mode=sql --name="select user from dual;"
CRITICAL - cannot connect to TESTDB. ORA-12545: Connect failed because target host or object does not exist (DBD ERROR: OCIServerAttach)

有人知道我做错了什么吗？
