Datastax Error : Cannot start node if snitch's data center (dc1) differs from previous data center (dc2)

-
Image
This error occurs when the node try to start and see it has snitch information which differ from previous data center. In my case, i was using DseSimpleSnitch which name the datacenter based on workload type. Previously i had enabled solr in dse default configuration file ( /etc/default/dse ) and datasenter name was Solr. Now i tried to start the dse with graph enabled, which change the name to datacenter SearchGraph which is default workload type name. CassandraDaemon.java:698 - Cannot start node if snitch's data center (Solr) differs from previous data center (SearchGraph). Please fix the snitch configuration, decommission and rebootstrap this node or use the flag -Dcassandra.ignore_dc=true Solution : 1) In the last line of  cassandra-env.sh  set in the jvm opts as given below : JVM_OPTS="$JVM_OPTS -Dcassandra.ignore_dc=true" 2) If it starts successfully, execute: nodetool repair nodetool cleanup

Configure Nagios plugin " check_logfiles " for scanning log file

-
I was checking for a nagios plugin which could filter the specified log file which i had mentioned and notify me whenever a warning or error appeared in log. Finally i get in hand check_logfile created by Gerhard Lausser. Check_logfiles is used to scan the lines of a file for regular expressions. Install the plugin on client system :  $ wget https://labs.consol.de/assets/downloads/nagios/check_logfiles-3.8.0.2.tar.gz $ tar xvzf check_logfiles-3.8.0.2.tar.gz $ cd check_logfiles-3.8.0.2/ $ ./configure $ make $ make install check_logfiles executable file will get installed on location "/usr/local/nagios/libexec" Configure Check Pattern : $ nano  /etc/nagios-plugins/config/check_log.cfg @searches = (   {     tag => 'Error',     logfile => '/var/logs/error.log',     criticalpatterns => 'Error',   } ); Here i am filtering pattern "Error" from log file which i had mentioned in logfile parameter section C
