+There are two methods available to monitor remote hosts. |
| 34 |
+</p> |
| 35 |
+ |
| 36 |
+<ol> |
| 37 |
+ <li> |
| 38 |
+ Use the <path>check_ssh</path> command to log on remotely to the system and |
| 39 |
+ execute the check you want to perform on that system |
| 40 |
+ </li> |
| 41 |
+ <li> |
| 42 |
+ Use the <e>NRPE</e> daemon on the remote host and have Nagios communicate to |
| 43 |
+ this daemon using the <path>check_nrpe</path> plugin |
| 44 |
+ </li> |
| 45 |
+</ol> |
| 46 |
+ |
| 47 |
+<p> |
| 48 |
+We first focus on using the NRPE method as it is the most popular one. |
| 49 |
+</p> |
| 50 |
+ |
| 51 |
+<p> |
| 52 |
+With NRPE, each remote host runs a daemon (the NRPE deamon) which allows the |
| 53 |
+main Nagios system to query for certain metrics. One can run the NRPE daemon by |
| 54 |
+itself or use an inetd program. I'll leave the inetd method as a nice exercise |
| 55 |
+to the reader and give an example for running NRPE by itself. |
| 56 |
+</p> |
| 57 |
+ |
| 58 |
+<p> |
| 59 |
+First install the NRPE plugin: |
| 60 |
+</p> |

+<pre caption="Installing the NRPE plugin"> |

+# <i>emerge nagios-nrpe</i> |

+</pre> |
| 65 |
+ |
| 66 |
+<p> |
| 67 |
TODO Inform what to install on systems that will not run the nagios interface, |
| 68 |
both for active (performs checks and communicates with the main nagios system) |
| 69 |
and passive (polled by main nagios system through check_ssh). |
