Cutting down or splitting a file to several smaller pieces have great benefits. A large file split into several smaller files can easilly fit in a CD or floppy disk or even transferred over the network. Splitting the file is possible using the split command.

Below is an example on how to use the split command:

Using split on a 5.3MB image.iso file:

split -b 1400k image.iso

It will generate 4 files with the following file sizes:

1404k xaa
1404k xab
1404k xac
1208k xad

To recreate the file, the cat command can be
used.

cat xa* > new-image.iso

The split and cat commands are provided by the coreutils package. Once the new new-image.iso file is restored, its possible to delete the other split files.

Note: To verify that the file has been correctly restored, use the command md5sum before and after splitting the file. Syntax: 

md5sum [filename]

SNMP stands for Simple Network Management Protocol and consists of three key components: managed devices, agents, and network-management systems (NMSs). A managed device is a node that has an SNMP agent and resides on a managed network. These devices can be routers and access server, switches and bridges, hubs, computer hosts, or printers. An agent is a software module residing within a device. This agent translates information into a compatible format with SNMP. An NMS runs monitoring applications. They provide the bulk of processing and memory resources required for network management.

SNMP MIBs, OIDs Overview

MIB stands for Management Information Base and is a collection of information organized hierarchically. These are accessed using a protocol such as SNMP. There are two types of MIBs: scalar and tabular. Scalar objects define a single object instance whereas tabular objects define multiple related object instances grouped in MIB tables.
MIB files for specific devices or systems can be downloaded from here

OIDs or Object Identifiers uniquely identify manged objects in a MIB hierarchy. This can be depicted as a tree, the levels of which are assigned by different organizations. Top level MIB object IDs (OIDs) belong to different standard organizations. Vendors define private branches including managed objects for their own products.

Here is a sample structure of an OID

Iso (1).org(3).dod(6).internet(1).private(4).transition(868).products(2).chassis(4).card(1).slotCps(2)­
.­cpsSlotSummary(1).cpsModuleTable(1).cpsModuleEntry(1).cpsModuleModel(3).3562.3

Most of the people may be looking for OID’s for Linux OID’s for CPU,Memory and Disk Statistics for this first you need to install SNMP server and clients. If you want to install SNMP server and client installation in linux check here

Disk Statistics

The snmpd.conf needs to be edited. Add the following (assuming a machine with a single ‘/’ partition):

disk / 100000 (or)

includeAllDisks 10% for all partitions and disks

The OIDs are as follows

Path where the disk is mounted: .1.3.6.1.4.1.2021.9.1.2.1
Path of the device for the partition: .1.3.6.1.4.1.2021.9.1.3.1
Total size of the disk/partion (kBytes): .1.3.6.1.4.1.2021.9.1.6.1
Available space on the disk: .1.3.6.1.4.1.2021.9.1.7.1
Used space on the disk: .1.3.6.1.4.1.2021.9.1.8.1
Percentage of space used on disk: .1.3.6.1.4.1.2021.9.1.9.1
Percentage of inodes used on disk: .1.3.6.1.4.1.2021.9.1.10.1

System Uptime: .1.3.6.1.2.1.1.3.0

Examples

These Commands you need to run on the SNMP server

Get available disk space for / on the target host

#snmpget -v 1 -c “community” target_name_or_ip .1.3.6.1.4.1.2021.9.1.7.1

this will return available disk space for the first entry in the ‘disk’ section of snmpd.conf; replace 1 with n for the nth entry

Get the 1-minute system load on the target host

#snmpget -v 1 -c “community” target_name_or_ip .1.3.6.1.4.1.2021.10.1.3.1

Get the 5-minute system load on the target host

#snmpget -v 1 -c “community” target_name_or_ip .1.3.6.1.4.1.2021.10.1.3.2

Get the 15-minute system load on the target host

#snmpget -v 1 -c “community” target_name_or_ip .1.3.6.1.4.1.2021.10.1.3.3

Get amount of available swap space on the target host

#snmpget -v 1 -c “community” target_name_or_ip .1.3.6.1.4.1.2021.4.4.0
