To install SNMP tools and libraries, run the following command. Install Net Snmp Perl Module' title='Install Net Snmp Perl Module' />How to monitor Linux servers with SNMP and Cacti. SNMP or Simple Network Management Protocol is used to gather data on what is going on within a device, such as load, hard disk states, bandwidth. These data are used by network monitoring tools such as Cacti to generate graphs for monitoring purposes. In a typical deployment of Cacti and SNMP, there will be one or more SNMP enabled devices, and a separate monitoring server where Cacti collects SNMP feeds from those devices. Please keep in mind that all the devices that need to be monitored must be SNMP enabled. In this tutorial, we will be configuring Cacti and SNMP on the same Linux server for demonstration purpose. Configure SNMP on Debian or Ubuntu. To install SNMP agent snmpd on a Debian based system, run the following command. Then edit its configuration like the following. Address udp 1. 61. Community and the source network is defined. Community 1. 72. 1. Location Earth. sys. Contact emaildomain. After editing the config file, restart snmpd. Configure SNMP on Cent. OS or RHELTo install SNMP tools and libraries, run the following command. Then edit an SNMP config file like the following. A user my. User is being defined with the community string my. Community and source network 1. User 1. 72. 1. 7. Community. my. User is added into the group my. Group and the permission of the group is defined. Group v. 1 my. User. Group v. User. view all included. Group any noauth exact all all none. Restart snmpd service, and add it to startup service list. Testing SNMPSNMP can be tested by running the snmpwalk command. If SNMP has been successfully configured, this command will generate a ton of output. Community 1. 72. 1. STRING Linux mrtg 3. Ubuntu SMP Tue Oct 9 1. UTC 2. 01. 2 x. 866. OID iso. 3. 6. 1.

Configure Cacti with SNMPIn this tutorial, we are setting up both Cacti and SNMP on the same Linux server. So go ahead and install Cacti on your Linux server on which SNMP was just configured. After installation, Cacti web interface can be accessed using the link http 1. S3 Gt-I9300 Pit File. IP address of your server. The paths during Cacti installation are usually correct. But they can be double checked if necessary. During the first time installation, the default username and password for Cacti are admin and admin. You will be forced to change the password after first login. Add and Manage Devices to Cacti. Cacti will poll devices based on SNMP string that was configured earlier. In this tutorial, we will add only the local server where SNMP is already enabled. To add devices, we login as admin and go to console in the Cacti admin panel. We click Console Devices. There may already be a device named localhost. We do not need it as we will create fresh graphs. We can delete this device from the list. We add a new device by using the add button. Next, we set the device parameters. Now that the device has been added, we specify the graph templates that we want to create. This section can be found in the bottom section of the page. And then we proceed to creating the graphs. Here, we create graphs for load average, RAM and hard disk, processor. Interface Graphs and 6. Counters. By default, Cacti uses 3. SNMP queries. 3. 2 bit counters are sufficient for most bandwidth graphs, but they do not work correctly for graphs greater than 1. Mbps. If it is known that the bandwidth will exceed more than 1. Mbps, it is always advisable to use 6. Using 6. 4 bit counters is not hard at all. Note It takes around 1. Cacti to populate new graphs. There are not alternatives to being patient. Creating Graph Trees. These snapshots illustrate how to create graph trees and how to add graph to those trees. We can verify the graph in the graph tree. User Management. Finally, we create a user with view permission to only the graph that we have created. Cacti has built in user management system, and it is highly customizable. After completing these steps, we can log in with the user user. And thus we have deployed a Cacti server in the network monitoring system. Cacti servers are stable, and can deal with tons of graphs without any problems.
