NAME
bsnmp-jails - an SNMP module provides statistics regarding FreeBSD jails
running on the system.
DESCRIPTION
bsnmp-jails is a module for bsnmpd(1) which monitors network and other
statistics for FreeBSD jails running on the system. These statistics are
gathered by the module.
MIBS
The counters will be available as a table under the following MIB:
.1.3.6.1.4.1.12325.1.1111
Or if the appropriate MIB.txt files have been installed:
enterprises.fokus.begemot.jails
The following SNMP MIBs are available for use (where X is the counter
index):
jails.jailCount
The number of jails running on the system.
jails.jailTable.jailEntry.jailIndex.X
The index of the jail in the table.
jails.jailTable.jailEntry.jailHost.X
The hostname of the jail.
jails.jailTable.jailEntry.jailInOctets.X
The number of octets received by the jail over the network.
jails.jailTable.jailEntry.jailInPackets.X
The number of packets received by the jail over the network.
jails.jailTable.jailEntry.jailOutOctets.X
The number of octets sent by the jail over the network.
jails.jailTable.jailEntry.jailOutPackets.X
The number of packets sent by the jail over the network.
jails.jailTable.jailEntry.jailProcesses.X
The number of processes running in the jail.
jails.jailTable.jailEntry.jailThreads.X
The number of threads running in the jail.
jails.jailTable.jailEntry.jailCpuTime.X
The amount of CPU time (in SNMP time ticks) the jail has
used.
jails.jailTable.jailEntry.jailDiskSpace.X
Amount of disk space taken by this jail. Zero means unknown.
jails.jailTable.jailEntry.jailDiskFiles.X
Number of files (inodes) in this jail. Zero means unknown.
jails.jailNetworkFilter
A tcpdump style filter for the network traffic. Only matched
traffic is counted in the jail statistics.
jails.jailRefreshInterval
The interval (in SNMP time ticks) between refreshing the jail
process statistics and checking which jails are running.
jails.jailMeasureInterval
The interval (in SNMP time ticks) between measuring the
amount of files and disk space used by the jail.
OPTIONS
To activate the bsnmp-jails module you must load the module in
/etc/snmpd.config
You can use the jailNetworkFilter SNMP MIB to configure which traffic to
count in the jail network statistics.
EXAMPLES
This example configures the module, and excludes traffic to/from the
10.0.0.0/8 network from the network monitoring.
The following would be added to /etc/snmpd.config:
begemotSnmpdModulePath."jails" = "/usr/local/lib/snmp_jails.so"
%jails
jailNetworkFilter = "not net 10.0.0.0/8"
jailMeasureInterval = 360000
