<modulesummary>Instrumentation Functions for STANDARD-MIB and SNMPv2-MIB</modulesummary>
<description>
<p>The module <c>snmp_standard_mib</c> implements the instrumentation functions for the
STANDARD-MIB and SNMPv2-MIB, and functions for configuring the database.
</p>
<p>The configuration files are described in the SNMP User's Manual.</p>
</description>
<funcs>
<func>
<name>configure(ConfDir) -> void()</name>
<fsummary>Configure the STANDARD-MIB and SNMPv2-MIB</fsummary>
<type>
<v>ConfDir = string()</v>
</type>
<desc>
<p>This function is called from the supervisor at system
start-up.
</p>
<p>Inserts all data in the configuration files into the
database and destroys all old rows with StorageType
<c>volatile</c>. The rows created from the configuration file
will have StorageType <c>nonVolatile</c>.
</p>
<p>All <c>snmp</c> counters are set to zero.
</p>
<p>If an error is found in the configuration file, it is
reported using the function <c>config_err/2</c> of the error
report module, and the function fails with the reason
<c>configuration_error</c>.
</p>
<p><c>ConfDir</c> is a string which points to the directory
where the configuration files are found.
</p>
<p>The configuration file read is: <c>standard.conf</c>.
</p>
</desc>
</func>
<func>
<name>inc(Name) -> void()</name>
<name>inc(Name, N) -> void()</name>
<fsummary>Increment a variable in the MIB</fsummary>
<type>
<v>Name = atom()</v>
<v>N = integer()</v>
</type>
<desc>
<p>Increments a variable in the MIB with <c>N</c>, or one if
<c>N</c> is not specified.</p>
</desc>
</func>
<func>
<name>reconfigure(ConfDir) -> void()</name>
<fsummary>Configure the STANDARD-MIB and SNMPv2-MIB</fsummary>
<type>
<v>ConfDir = string()</v>
</type>
<desc>
<p>Inserts all data in the configuration files into the
database and destroys all old data, including the rows with
StorageType <c>nonVolatile</c>. The rows created from the
configuration file will have StorageType <c>nonVolatile</c>.
</p>
<p>Thus, the data in the SNMP-STANDARD-MIB and SNMPv2-MIB,
after this function has been called, is from the
configuration files.
</p>
<p>All <c>snmp</c> counters are set to zero.
</p>
<p>If an error is found in the configuration file, it is
reported using the function <c>config_err/2</c> of the error
report module, and the function fails with the reason
<c>configuration_error</c>.
</p>
<p><c>ConfDir</c> is a string which points to the directory
where the configuration files are found.
</p>
<p>The configuration file read is: <c>standard.conf</c>.
</p>
</desc>
</func>
<func>
<name>reset() -> void()</name>
<fsummary>Reset all <c>snmp</c>counters to 0</fsummary>
<desc>
<p>Resets all <c>snmp</c> counters to 0.</p>
</desc>
</func>
<func>
<name>sys_up_time() -> Time</name>
<fsummary>Get the system up time</fsummary>
<type>
<v>Time = int()</v>
</type>
<desc>
<p>Gets the system up time in hundredth of a second.</p>
</desc>
</func>
