CHECK_NRPE: Received 0 Bytes From Daemon error pops up during Linux server configuration in Nagios XI using a NRPE agent.<\/p>\n
With several issues that I faced last week in setting up NRPE agent in linux so that I can Monitor linux server, one more issue that I found was,\u00a0CHECK_NRPE: Received 0 Bytes From Daemon message that pops up in Nagios XI console.<\/p>\n
Solution<\/span><\/p>\n 1. Make sure that NRPE services are started properly before further troubleshooting.<\/p>\n 2. Make sure that the values in nrpe.cfg file are properly declared and are allowing Nagios IP for performing the request.<\/p>\n 3. Log into Linux server where NRPE is available and check below command,<\/p>\n cat \/usr\/local\/nagios\/etc\/nrpe.cfg | grep blame<\/p>\n 4. Output for above command should be,<\/p>\n dont_blame_nrpe=1<\/p>\n 5. Without this directive set to a value of \u201c1\u201d, arguments will not be accepted for any checks other than those specified in the nrpe.cfg file itself. If the \u201cdont_blame_nrpe\u201d directive is set to \u201c0\u201d, you will need to edit \/usr\/local\/nagios\/etc\/nrpe.cfg and set dont_blame_nrpe=1.<\/p>\n 6. Make sure that the arguments that you are checking are done through command prompt first and then through Nagios XI console.<\/p>\n If you are checking for memory, use check_mem command first without any check_nrpe command. If you checking for users who are logged in on Linux, you first check the users command separately and then use check_nrpe.
