What is the early stage ?? Www.2cto.com (1) MRTG must be based on the SNMP service. therefore, make sure that your system has enabled this service and modify the SNMP configuration: # vi/etc/snmp/snmpd. conf, replace row 62: access notConfigGroup "" any noauth exact systemview none with access notConfigGroup "" any noauth exact mib2 none, and remove the annotation symbol before row 89th, changed to view mib2 encoded Ded .iso.org. dod. internet. mgmt. mib-2 fc www.2cto.com (2) linux Mrtg monitors host traffic starting http and snmp services: first, check whether the two services are enabled when the system starts. # chkconfig -- list | grep nginx is not started. if so, modify the startup mode. Start it by yourself: # chkconfig -- level 35 nginx on uses the same settings for the snmpd service. now, manually start # service nginx start # service snmpd start ?? Again? Why does it happen?
