How to pass MIB to the Manager
------------------------------
Q. How to make use of random MIBs at my Manager application?
A. Starting from PySNMP 4.3.x, plain-text (ASN.1) MIBs can be
automatically parsed into PySNMP form by the
`PySMI <http://snmplabs.com/pysmi/>`_ tool. PySNMP will call PySMI
automatically, parsed PySNMP MIB will be cached in
$HOME/.pysnmp/mibs/ (default location).
MIB compiler could be configured to search for plain-text
MIBs at multiple local and remote locations. As for remote
MIB repos, you are welcome to use our collection of ASN.1
MIB files at
`http://mibs.snmplabs.com/asn1/ <http://mibs.snmplabs.com/asn1/>`_
as shown below.
.. literalinclude:: /../../examples/hlapi/asyncore/sync/manager/cmdgen/custom-asn1-mib-search-path.py
:start-after: """#
:language: python
.. code:
:language: python
# Configure the SNMP engine with access to the
# common Linux ASN.1 (Textual) MIB directories...
from pysnmp import hlapi
from pysnmp.smi import compiler
engine = hlapi.Engine()
builder = engine.getMibBuilder()
compiler.addMibCompiler(builder, sources=[
'/usr/share/snmp/mibs',
os.path.expanduser('~/.snmp/mibs'),
'http://mibs.snmplabs.com/asn1/@mib@',
])
:download:`Download</../../examples/hlapi/asyncore/sync/manager/cmdgen/custom-asn1-mib-search-path.py>` script.
Alternatively, you can invoke the
`mibdump.py <http://snmplabs.com/pysmi/mibdump.html>`_
(shipped with PySMI) by hand and this way compile plain-text MIB
into PySNMP format. Once the compiled MIBs are stored in a directory,
add the directory to your MibBuilder's MibSources.
.. code::
builder = engine.getMibBuilder()
# Make ./mibs available to all OIDs that are created
# e.g. with "MIB-NAME-MIB::identifier"
builder.addMibSources(builder_module.DirMibSource(
os.path.join( HERE, 'mibs')
))
