2013 in CentOS, Monitoring, Networking, Package Management, RedHat and FriendsCacti is a network graphing tool similar to MRTG. How do I install and configure common options to collect SNMP data and various snmp information snmp error cacti other data (such as system load, network link status, hard disk space, logged

in users etc) into an RRD? From the official project site:
Cacti is a complete frontend to RRDTool, it stores cacti add device snmp error all of the necessary information to create graphs and populate them with data in a MySQL database. The frontend is completely PHP driven. Along with being able to maintain Graphs, Data Sources,Snmp Error Cacti Ubuntu
and Round Robin Archives in a database, cacti handles the data gathering. There is also SNMP support for those used to creating traffic graphs with MRTG.Required software(s)You need to install the following software on RHEL / Fedora / CentOS Linux:MySQL Server : Store cacti data.NET-SNMP server - SNMP (Simple Network Management Protocol) is a protocol used for network management.PHP with net-snmp module - Access snmp get timeout for host SNMP data using PHP.Apache / lighttpd / ngnix webserver : Web server to display graphs created with PHP and RRDTOOL.Install the Cacti software on CentOS / RHELFirst, login as root user and type the following command to install mysql, apache and php: # yum install mysql-server mysql php-mysql php-pear php-common php-gd php-devel php php-mbstring php-cli php-snmp php-pear-Net-SMTP php-mysql httpdConfigure MySQL serverFirst, set root password: # mysqladmin -u root password NEWPASSWORDCreate cacti MySQL databaseCreate a database called cacti, enter: # mysql -u root -p -e 'create database cacti' Create a user called cacti with a password called zYn95ph43zYtq, enter: # mysql -u root -pmysql> GRANT ALL ON cacti.* TO cacti@localhost IDENTIFIED BY 'zYn95ph43zYtq'; mysql> FLUSH privileges; mysql> \qInstall snmpdType the following command to install net-snmpd # yum install net-snmp-utils php-snmp net-snmp-libs Configure snmpd, open /etc/snmp/snmpd.conf # vi /etc/snmp/snmpd.conf Append / modify it as follows (see snmpd.conf man page for details):com2sec local localhost public group MyRWGroup v1 local group MyRWGroup v2c local group MyRWGroup usm local view all included .1 80 access MyRWGroup "" any noauth exact all all none syslocation Unknown (edit /etc/snmp/snmpd.conf) syscontact Root
2013 Authored by Sarmed Rahman 16 Comments SNMP (or Simple Network Management Protocol) is used to gather data on what is going on within a device, such as
Cacti Snmp Error Windows
load, hard disk states, bandwidth. These data are used by network monitoring tools such
Snmp Error Cacti Centos
as Cacti to generate graphs for monitoring purposes. In a typical deployment of Cacti and SNMP, there will be one or cacti download 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 http://www.cyberciti.biz/faq/fedora-rhel-install-cacti-monitoring-rrd-software/ 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. root@server:~# apt-get install snmpd
Then edit its configuration like the following. root@server:~# vim /etc/snmp/snmpd.conf # this will make snmpd listen on all interfaces agentAddress udp:161 # a read only community 'myCommunity' and http://xmodulo.com/monitor-linux-servers-snmp-cacti.html the source network is defined rocommunity myCommunity 172.17.1.0/24 sysLocation Earth sysContact email@domain.tld After editing the config file, restart snmpd. root@server:~# service snmpd restart Configure SNMP on CentOS or RHEL To install SNMP tools and libraries, run the following command. root@server:~# sudo yum install net-snmp Then edit an SNMP config file like the following. root@server:~# vim /etc/snmp/snmpd.conf # A user 'myUser' is being defined with the community string 'myCommunity' and source network 172.17.1.0/24 com2sec myUser 172.17.1.0/24 myCommunity # myUser is added into the group 'myGroup' and the permission of the group is defined group myGroup v1 myUser group myGroup v2c myUser view all included .1 access myGroup "" any noauth exact all all none root@server:~# service snmpd restart root@server:~# chkconfig snmpd on Restart snmpd service, and add it to startup service list. Testing SNMP SNMP can be tested by running the snmpwalk command. If SNMP has been successfully configured, this command will generate a ton of output. root@server:~# snmpwalk -c myCommunity 172.17.1.44 -v1 iso.3.6.1.2.1.1.1.0 = STRING: "Linux mrtg 3.5.0-17-generic #28-Ubuntu SMP Tue Oct 9 19:31:23 UTC 2012 x86_64" iso.3.6.1.2.1.1.2.0 = OID: iso.3.6.1.4.1.8072.3.2.10 iso.3.6.1.2.1.1.3.0 = Timeticks: (2097) 0:00:20.97 ~~ OUTPUT TRUNCATED ~~ iso.3.6.1.2.1.92.1.1.2.0 = Gauge32: 1440 iso.3.6.1.2.1.92.1.2.1.0 = Counter32: 1 iso.3.6.1.2.1.92.1.2.2.0 = Counter32: 0 iso.3.6.1.2.1.92.1.3.1.1.2.7.100.101.102.97Start here for a quick overview of the site Help Center Detailed answers to any questions you might have Meta Discuss the workings http://serverfault.com/questions/379467/frequent-snmp-error-with-cacti and policies of this site About Us Learn more about Stack Overflow https://www.youtube.com/watch?v=zQmE4IwNVvo the company Business Learn more about hiring developers or posting ads with us Server Fault Questions Tags Users Badges Unanswered Ask Question _ Server Fault is a question and answer site for system and network administrators.

But the error is not consistent, not even for the same device. Here's snmp error cacti what I already have checked: Sometimes a device shows that "SNMP error" message even when it did not had that error an hour before, and vice versa. I tried this with several different Cacti releases, installed on different OS (Debian squeeze: 0.8.7g-1+squeeze1, Debian Sid: 0.8.7i-3, CentOS 6.0: 0.8.7i-2.el6) tried both from a local (192.168.1.xy) network and from a different data center so I don't think it is a network problem reinstalled the Cacti database, rerun the scripts to install my devices. Now different devices have that error when executing a snmpwalk or snmpgetnext command from the command line, it is always successful increasing the timeout to 20000 (20 seconds) and the retry count to 10 does not make a difference The cacti.log says: 04/14/2012 02:10:19 PM - CMDPHP: Poller[0] WARNING: SNMP GetNext Timeout for Host:'s0026.mydomain.de', and OID:'.1.3.6.1.2.1.1.3.0' 04/14/2012 02:10:20 PM - CMDPHP: Poller[0] WARNING: SNMP GetNext Timeout for Host:'s0026.mydomain.de', and OID:'.1.3' However, when executing snmpget or snmpget with that from the command line a proper response is returned immediately. monitoring network-monitoring cacti share|improve this question asked Apr 14 '12 at 14:2

Uploaded on Oct 13, 2011Get Beacon-Find My Droid: Lightweight & reliable: http://bit.ly/LpFcxvThis video describes the installation of Cacti in Ubuntu which is a Debian distribution. Cacti is a PHP based web graphing tool that is free to download and install. Cacti could be practically installed in any operating system, but the easiest and cheapest would be to have a Linux distribution such as Ubuntu. Once the installation is complete, you are taken in to a practical environment where few ports of a real-world 3com switch is added in to the graphing. Then a tree the new device is added in to the 'Default Tree' as a 'Host'. Individual graphs can be added using 'Graph' option over there.Few minutes after adding the device, the newly developed graphs are starting to show up.Follow this link to know answers for the following:01. Why should I use cacti-spine?02. Created device, but device status is 'unknown', and doesn't change...03. What if we have a lot of devices to monitor?04. Every thing went quite OK, but graphs not shown? Category Education License Standard YouTube License Show more Show less Loading...
