Become an author. A large part of being a system administrator is collecting accurate information about your servers and infrastructure.
There are a number of tools and options for gathering and processing this type of information. Many of them are built upon a technology called SNMP.
SNMP stands for simple network management protocol. It is a way that servers can share information about their current state, and also a channel through which an administer can modify pre-defined values. While the protocol itself is very simple, the structure of programs that implement SNMP can be very complex. In our last guide, we learned about the basics of the SNMP protocol. In this guide, we will begin to demonstrate how to setup the tools to communicate using SNMP. We will be using two Ubuntu We can begin to explore how SNMP can be implemented on a system by installing the daemon and tools on some Ubuntu systems.
We will use two servers, one will contain the manager portion, while the other server will have the agent. We could choose to install the agent on the manager machine as well, but keeping them separate makes it easier to demonstrate what functionality is provided by each component.
On the first server, update the apt database and install the manager component. Along with this, we will also download another package called snmp-mibs-downloader which contains some proprietary information about standard MIBs that allow us to access most of the MIB tree by name:. On our second server, the one that we will be interacting with that will run the daemon, we can install the necessary components by typing:. As we mentioned above, most of the bulk of the work happens in the agent component, so our configuration is actually pretty easy on this machine.
We just need to modify one file to make sure that our client can use the extra MIB data we installed. In this file, there are a few comments and a single un-commented line. To allow the manager to import the MIB files, we simply need to comment out the mibs : line:.
We are now finished configuring the manager portion, but we will still need to use this server to help us configure our agent computer. As a true client-server system, the agent computer does not have any of the external tools needed to configure its own SNMP setup.
We can modify some configuration files to make some changes, but most of the changes we need to make will be done by connecting to our agent server from our management server.
Inside, we will have to make a few changes. These will mainly be used to bootstrap our configuration so that we can manage it from our other server.Buy or Renew. Find A Community.

The lines for this should look like this:. Note that this will allow ANY system to query your machine. You will need to adjust this to limit SNMP access to your device. You will now want to change your Read-only SNMP string from public to a custom string of your choosing, as below:. Note: Removing -V systemonly from the line will allow access to the entire MIB tree and not restrict it to the system part of the tree.
In your specific case, it would be 1.SNMP - Работа с протоколом и его библиотеками

Thanks for all you do for us and keep up the good work! Very easy to work with and for a freeware tool, the support guys are just amazing. I was just thinking if we buy a product the support will be top notch - Surendra, Team Lead, Cisco Systems. I have been working with the package for a couple of weeks now and it looks very good.
I am using it to test a real time frequency and time agent for snmp v1, v2 and v3 and it's looking good. Simple yet effective tool for a small medium organisation where very few IT users are manning more than a server. This tool is easy to use and allows you to view, configure and parse SNMP traps. It listens to one or more port at a time and the trap can be sent from any host. SNMP trap parser is used to configure and parse the trap events. Traps contain cryptic information not easily understandable to the users, so trap parsers translate or parse traps into understandable, meaningful information.
It allows you to add a row to the existing table, view graphs, index editor etc.
Decoder is used to decode the SNMP debug messages. This tool converts Hex values into human readable messages.

Some good features of Cacti include:. Cacti has a number of dependencies that need to be installed and configured before you can deploy Cacti server itself.
This guide will cover the installation of these dependencies one by one:. We now need to install php and some php modules required by cacti.
Run the following commands to get everything and installed. Make sure they are installed. You can check your php version using the command:. The last package installation step is for Cacti and snmp packages. Install these packages using the command:. From here, we have to configure database settings for Cacti and initiate setup on the web interface.
Cacti will check if all requirements are satisfied. You may need to make some changes depending on warnings level. When prompted to change the password for the admin user, provide a new password and confirm. You will then get access to Cacti interface which looks like below:. Add the local Cacti server for monitoring. Login to Cacti as admin user and go to:. Sign in. Log into your account.
