The error “CHECK_NRPE: Error – Could not complete SSL handshake.” is usually caused by a mssing or wrong “allowed_hosts” configuration in /etc/nagios/nrpe. cfg. With an active debug option in the same config-file the active “allowed_hosts” setting is reported to the syslog (see log snippet above).
Step 1: “CHECK_NRPE: Error – SSL handshake failed” is sometimes (from what I’ve seen) an edge client issue. Step 2: Nagios clients typically store the nrpe-file.cfg file (provided by nagios-nrpe or nrpe-package) in /etc/nagios/nrpe.cfg (if installed from RPM).
In short, the NRPE handshake SSL error occurs when the NRPE server is having trouble communicating with the Nagios server. Today we saw how our support engineers solved this problem by adding the correct nrpe location file to the Nagios Into ip host. AVOID SERVER CRASH!
There are some mixed results, although most of them are simply due to the Nagios XI server’s IP address not being allowed to connect to NRPE. This can be specified in one of two places, depending on whether you are running xinetd when the daemon starts NRPE, and whether NRPE has its own fully committed daemon.
What is the importance of Nagios server in Nagios?
Allows Nagios to read its configuration from an entire directory, which helps you decide how to define individual electronic files. Uses topology to determine dependencies. Monitoring network services such as HTTP, SMTP, HTTP, SNMP, SSH, FTP, POP, etc. Helps to identify network nodes based on hierarchical parent nodes.
What is the difference between Nagios and Nagios XI?
Nagios Core requires up-to-date technical resources to install and configure your current organization’s monitoring infrastructure, as well as to perform day-to-day tasks. On the other hand, Nagios XI eliminates the need for potential customers to understand the command line with a user-friendly interface designed for non-technical users.
