Datastax Error : Error initializing cluster data

-



I was getting the following error in Opscenter continuously and it get resolved automatically after some time.

Error initializing cluster data: The request to 
/APP_Live/keyspaces?ksfields=column_families%2Creplica_placement_strategy%2Cstrategy_options%2Cis_system%2Cdurable_writes%2Cskip_repair%2Cuser_types%2Cuser_functions%2Cuser_aggregates&cffields=solr_core%2Ccreate_query%2Cis_in_memory%2Ctiers timed out after 10 seconds.. 

If you continue to see this error message, you can workaround this timeout by setting [ui].default_api_timeout to a value larger than 10 in opscenterd.conf and restarting opscenterd. 
Note that this is a workaround and you should also contact DataStax 
Support to follow up.


Solution :

Workaround of this timeout is by setting [ui].default_api_timeout to a value larger than 10 in opscenterd.conf and restarting opscenterd.

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

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
