.Os rrdbot
.Sh NAME
.Nm rddbotd
.Nd an SNMP poller which writes to an round robin database
.Sh SYNOPSIS
.Nm
.Op Fl M
.Op Fl c Ar confdir
.Op Fl w Ar workdir
.Op Fl m Ar mibdir
.Op Fl d Ar debuglevel
.Op Fl p Ar pidfile
.Op Fl r Ar retries
.Op Fl t Ar timeout
.Nm
.Fl V
.Sh DESCRIPTION
.Nm
is an SNMP polling daemon which writes the polled values to an
.Xr rrdtool 1
RRD database. An can poll many different SNMP sources in an efficient manner.
.Pp
Table queries are supported, where the OID index of a certain value is not
known beforehand, or may change regularly.
.Pp
In addition multiple SNMP agents may be specified for a certain value. If
one SNMP agent cannot be contacted or errors for some reason, another one
will be tried.
.Pp
The configuration (eg: SNMP sources, polling intervals) are located in files
in a directory, with one configuration file per RRD. The format of the
configuration files are described in:
.Xr rrdbot.conf 5
.Sh OPTIONS
The options are as follows.
.Bl -tag -width Fl
.It Fl c Ar confdir
The directory in which configuration files are stored. See below for info
on the various file locations.
.It Fl d Ar debuglevel
Don't detach from the console and run as a daemon. In addition the
.Ar debuglevel
argument specifies what level of error messages to display. 0 being
the least, 4 the most.
.It Fl m Ar mibdir
The directory in which to look for MIB files. The default directory is
usually sufficient.
.It Fl M
Display MIB parsing warnings.
.It Fl p Ar pidfile
Specifies a location for the a process id file to be written to. This file
contains the process id of
.Nm
and can be used to stop the daemon.
.It Fl r Ar retries
The number of times to retry sending an SNMP packet. Defaults to 3 retries.
.It Fl t Ar timeout
The amount of time (in seconds) to wait for an SNMP response. Defaults to
5 seconds.
.It Fl V
Prints the version of
.Nm
and the locations of the configuration files, RRD files etc.
.It Fl w Ar workdir
The default directory where to look for RRD files. See below for info on
the various file locations.
.El
.Sh FILE LOCATIONS
To determine the default location for the configuration files and RRD files
run this command:
.Bd -literal -offset indent
# rrdbotd -V
.Ed
.Pp
The configuration files for SNMP pollers are laid out in a directory tree,
with one file per RRD. Subdirectories can be used to organize the
configuration files. The contents of the configuration files are described
in
.Xr rrdbot.conf 5 .
.Pp
By default the RRD files mirror the directory structure and names of the
configuration files, with an
.Pa .rrd
extension appended to the filename.
.Pp
For example if your configuration files are in a structure like the following:
.Bd -literal -offset indent
/usr/local/etc/rrdbot/
gateways/
gateway-load.conf
gateway-traffic.conf
temperature/
inside-temperature.conf
outside-temperature.conf
machine-load.conf
.Ed
.Pp
Then the default RRD files would be in a similar directory structure:
.Bd -literal -offset indent
/var/db/rrdbot/
gateways/
gateway-load.conf.rrd
gateway-traffic.conf.rrd
temperature/
inside-temperature.conf.rrd
outside-temperature.conf.rrd
machine-load.conf.rrd
.Ed
.Pp
The default location for an RRD file can be overridden by using the
.Ar rrd
option in the configuration file.
.Pp
You can use the
.Xr rrdbot-create 8
tool to create the needed RRD files in the appropriate places.
