| - | ====== Gateway monitoring ====== | ||
| - | ===== Monit daemon ===== | ||
| - | |||
| - | Monit is an open source supervision tool. It can monitor daemons, system resources, remote hosts or programs. It is recommended to use monit to monitor your applications. Please see [[https://mmonit.com/monit/|online documentation]]. | ||
| - | |||
| - | The command ''monit status'' returns the status of all supervised services. Services can be started/stopped with monit using the commands ''monit start <name>'' and ''monit stop <name>''. | ||
| - | |||
| - | The monit configuration is made in the directory **''/etc/monit.d''**. It is a directory in which you have to add small scripts to describe what you want to do accordingly to monit specification. | ||
| - | |||
| - | ===== Watchdog ===== | ||
| - | |||
| - | Watchdog is handled by monit daemon. | ||
| - | |||
| - | ===== SNMP agent ===== | ||
| - | |||
| - | Simple Network Management Protocol (SNMP) is a protocol used for monitoring network equipments. | ||
| - | The data SNMP management is organized in a management information base (MIB). | ||
| - | SNMP agent on Kerlink gateways is based on net-snmp ([[http://net-snmp.sourceforge.net/|Net-SNMP]]). | ||
| - | It is included by default with the firmware, however, since this is a generic agent, a few modifications are required to use it. | ||
| - | |||
| - | ==== Configuration ==== | ||
| - | Configuration file must be in ''/etc/snmp/''. A default configuration file is present in this directory. | ||
| - | |||
| - | |||
| - | ==== Manual Execution ==== | ||
| - | To execute ''snmp'' agent, just type:\\ | ||
| - | snmpd | ||
| - | |||
| - | ==== Automatic Execution ==== | ||
| - | To automatically execute ''snmpd'' at boot time, a script named ''snmpd.init'' needs to be created in a new folder ''/user/snmp/bin/''. | ||
| - | |||
| - | * Copy the following script under ''/user/snmp/bin/snmpd.init''. | ||
| - | <code init snmpd.init> | ||
| - | #! /bin/sh -e | ||
| - | ### BEGIN INIT INFO | ||

| - | </code> | ||
| - | |||
| - | * Apply executable right to the script: | ||
| - | <code>chmod 700 /user/snmp/bin/snmpd.init</code> | ||
| - | |||
| - | * Create a symbolic link in ''rcU.d'' to the script so so it is executed at boot time. | ||
| - | <code>ln -s /user/snmp/bin/snmpd.init /user/rootfs_rw/etc/rcU.d/S59snmpd</code> | ||
| - | |||
| - | * Create a symbolic link in ''rcU.d'' to the script so so it is executed when the system halts. | ||
| - | <code>ln -s /user/snmp/bin/snmpd.init /user/rootfs_rw/etc/rcK.d/K59snmpd</code> | ||
| - | |||
| - | * Reboot the Wirnet™ iBTS (''reboot'' command) or type the below command to start ''snmpd'': | ||
| - | <code>/etc/rcU.d/S59snmpd start</code> | ||
| - | |||
| - | ===== Supported MIBs ===== | ||
| - | The following MIBs are supported:\\ | ||
| - | * mib2 (RFC1213) | ||
| - | //mibII/vacm_conf\\ | ||
| - | mibII/tcpTable\\ | ||
| - | mibII/udpTable\\ | ||
| - | mibII/system// | ||
| - | * if-mib | ||
| - | //if-mib/ifTable\\ | ||
| - | if-mib/ifTable/ifTable\\ | ||
| - | if-mib/ifTable/ifTable_interface// | ||
| - | |||
