Monitors Troubleshoot
|
General configuration mistakes on NS side |
| Possible Reasons #1 | For running any monitor test, we need to do the basic configuration on appliance side. |
| Steps to Diagnose |
1.) Lps port is not defined in scenario. 2.) Lps is running on different port, but in scenario Lps port is different. 3.) Lps port defined is correct in scenario and Lps file, but Lps port is not running. 4.) The IP in server.conf is not same as of /etc/hosts resulting not able to make the connection. 5.) Server must be present in Server.conf for the given topology with status 1(i.e active) and agent field 2 or 3. 6.) JSON keyword should be mentioned in Scenario. 7.) Topology keyword should be mentioned in Scenario. 8.) All configurations should be correct in Json file. |

General configuration mistakes on server side |
| Possible Reasons #1 | For running any monitor test, we need to do the basic configurations on server side. |
| Steps to Diagnose |
1.) cmon should be running in appliance/server side. 2.) Cmon.env is not present/correct on the server, resulting the un-updated topology (Autoscaling). 3.) Server must be present in Server.conf for the given topology with status 1(i.e active) and agent field 2 or 3 . 4.) Standalone for shell based monitor (run the standalone on the server with the programme name of monitor in bin directory) 5.) Standalone for java based monitor( run the standalone on server with the program name of monitor along with the mandatory options and the type) 6.) After running the standalone, check for error and debug logs on server side.

Access Log Data is not coming |
| Possible Reasons #1 | Check lps is running or not. Check fields of logs. |
| Steps to Diagnose |
1.) Firstly we have to check lps is running or not (Run LPS) and check the lps connectivity
2.) Secondly Logs are appending or not.3.) fields are correct on not (Json Configuration).Change the delimiter from space to tab in the Json.     |

|
System metrics data is not coming or Tier Servers are missing |
| Possible Reasons #1 | Configuration mistakes in topology.
Field mapping of Tier.conf & Server.conf |
| Steps to Diagnose |
1.) We have to check topology i.e. Tier.conf and Server.conf, all the config of both are correct. Servers are auto scaled properly. To check whether the server is active or not, we have to run a standalone of that particular monitor whose data is not coming.

2.) If you find given mbeans then data will be displayed otherwise no data will be present for jetty monitors. |
| Commands to validate |
Jetty Mbeans are not present on server side. We have dumped mbeans and found below stats Mbeans required: org.eclipse.jetty.util.thread:type=queuedthreadpool,id=* we can found mbean mbeans through below stand alone :- |
| Solution | The mandatory jars should be present on the server side and version of Jars should match. |
|
Not getting data of process stats monitor of particular server |
| Possible Reasons #1 | Auto scaling issue. |
| Steps to Diagnose | After debugging the issue we came to know that in topology the last 5th field was zero (0 )which indicates that server is not autoscaled due which data was not showing.
Check the process is running or not on server. |
| Commands to validate |
“Pass the correct data in cmon.env like Tier name and Server Ip. CMON_OPTS=””-Dcom.sun.management.jmxremote=true -Dcom.sun.management.jmxremote.port=9999 -Dcom.sun.management.jmxremote.ssl=false -Dcom.sun.management.jmxremote.authenticate=false -Dcom.sun.management.jmxremote.rmi.port=9999 -Djava.rmi.server.hostname=10.10.30.74″” |

Large number of vectors are getting added and deleted |
| Possible Reasons #1 | Vectors are getting added and delete in Server frequently |
| Steps to Diagnose | As our environment is dynamic, vector will get added and deleted as per the requirement and load. But in some cases, vector gets deleted and within a sample of few sec/minutes, same vector gets added again (mostly in case of network related monitors). Here every time monitor will delete it.
To avoid this, we have keyword : /maxVecPersistCount: which will not delete vector until given samples. |
| Commands to validate |
We will add this keyword in json file .
{ “”app””: [ { “”options””: “”ProcessorStats””, “”lastUpdatedTime””: -1, “”app-name””: “”default”” } ], “”lastUpdatedTime””: 1576479094187, “”std-mon-name””: “”/maxVecPersistCount:10″”, “”enabled””: true } |
| Solution | “Need to add keyword maxVecPersistCount in option in json |
| Possible Reasons #2 | Client had applied monitor for all process but they do not need all processes |
| Steps to Diagnose | There are few monitors which gives us process-wise data. By default if we apply those monitors, we get data of all the process. So, to get data for specific process, we provide process names which we want to monitor . We pass it in json under argument field. |
| Commands to validate | We will add this keyword in json file . { “”app””: [ { “”options””: “”ProcessorStats””, “”lastUpdatedTime””: -1, “”app-name””: “”default”” } ], “”lastUpdatedTime””: 1576479094187, “”std-mon-name””: “”/args: CavWMon,java /interval:10000 /trnum:$MON_TEST_RUN /parnum:$MON_PARTITION_IDX””, “”enabled””: true } |
| Solution | Need to add process in under args option in json |
|
kubernetes IP monitor not running |
| Possible Reasons #1 | Wrong token pass ni the token file. In the JSON , there is some configuration mistake.

Data not coming in Kubernetes monitor |
| Possible Reasons #1 | 1. Kubernetes IP monitor is not running.
2.Tier-server mapping. 3. Check json Configuration. |
| Steps to Diagnose | 1. Kubernetes IP monitor is not running checked by the above standalone.
2. Tier-server mapping where that cluster present in topology or not with that check autoscaling has been done and in “Server.conf” in last 5th –field and last field is enable or disable. 3. Check the configuration of json(json should me made from front end only), All mandatory options are there or not. 4. App-name is passed correct or not . 5. Check monitor.log, cmon.log, error and debug log some time connection is break or many other reasons or root cause we found in these logs only. |

If user can face the same issue in OUTBOUND mode like data is not coming in Kubernetes Ip monitor or any Kubernetes monitor. |
| Possible Reasons #1 | 1. When the test is running in outbound mode firstly we have to check the keyword in scenario is correct or not.
2. Some configuration issue in cmon.env(auto-scaling) 3. NDC port is correct and NDC is running or not. |
| Steps to Diagnose | 1. Open cmon.env and check NDC port is correct or not.
2. If port is correct NDC is running or not. 3. Run nsu_server_admin command. |
| Commands to validate | “Outbound Keyword
ENABLE_OUTBOUND_CONNECTION NDC_LPS_PORT 7876 ps -ef | grep ‘ndc’ nsu_server_admin -s MachineIP -H hostIP -N ndc port -c ‘options'” |
| Solution | All configuration should be correct. mendatory keywords should be present in the scenario. connectvity with the NDC port. |

Redis data is not coming
|
| Possible Reasons #1 | Redis application is not running |
| Steps to Diagnose | Check redis process is running or not |
| Commands to validate | nsu_server_admin – s ip -c “ps -ef”|grep redis |
| Solution | Need to Set default port 6379 for redisDB and restart the application again. |
| Possible Reasons #2 | Port passed in json is wrong |
| Steps to Diagnose | Check the redis port |
| Commands to validate | nsu_server_admin – s ip -c “netsta -natp”|grep “redis-port” |
| Solution | Need to give full acccess/adim privilages to the mentioned user for redisDB. |
| Possible Reasons #3 | Redis db password is wrong |
| Steps to Diagnose | Check the query on Redis db with same user. Wheather query is giving output or not |
| Commands to validate | nsu_server_admin -s 127.0.0.1 -c “java -DCAV_MON_HOME=/home/cavisson/monitors -cp /home/cavisson/monitors/lib/*

JavaGCJMX data is not coming |
| Possible Reasons #1 | jmx port is not enabled for that java process |
| Steps to Diagnose | Check the connectivity with jmx port using telnet |
| Commands to validate | telnet <host> <port> |
| Solution | Port is accessible from ND-Machine |
| Possible Reasons #2 | jmx remote is not true |
| Steps to Diagnose | Check jmx configuration of the process |
| Commands to validate | JMX port configuration
{“-Dcom.sun.management.jmxremote=true -Dcom.sun.management.jmxremote.port=7991 -Dcom.sun.management.jmxremote.ssl=false -Dcom.sun.management.jmxremote.authenticate=false -Djava.rmi.server.hostname=10.10.30.124”} |
| Solution | Need to make the connectivity with jmx port. |
| Possible Reasons #3 | rmi server hostname is not provided |
| Steps to Diagnose | check the pid if javaGCJMX is configured on java process PID
check PID file if monitor is configured on PId file |
| Commands to validate | nsu_server_admin -s 127.0.0.1 -c “ps -ef”|grep
nsu_server_admin -s 127.0.0.1 -c “java -DCAV_MON_HOME=/home/cavisson/monitors -cp /home/cavisson/monitors/lib/*:/home/cavisson/monitors/custom:/home/cavisson/monitors/bin/CavMonAgent.jar:/home/cavisson/apps/jdk1.8.0_161/lib/tools.jar:. com.cavisson.monitoring.java.gc_jmx.cm_java_gc_jmx -h 127.0.0.1 -p 7991 -j SunHotSpot” |

Not getting data in DB Query |
| Possible Reasons #1 | 1. Authentication issue: db password is different and not in encoded form.
2. Connection closed and retry for particular monitor. 3. csv files dumped in tables but data go to diff column instead of csv column due to different in sequence of data and system time and server time differ from each other. |
| Steps to Diagnose | Check json configuration for that monitors
Check monitor.log Check in current partition that all csv files are present. eg..mssql_process_done.txtcheck csv files data dumped in table or not. |
| Commands to validate |
path: NS_WDIR/TRNo./Partition/reports/csv “neu_validate_db_data -n 1211 -p 2020xxxxxx -o ns -l nsu_server_admin -s 10.10.220.2 -M “”mssql: -h 10.10.220.2 -p 1433 |
| Solution | csv file should be updated timely.
Need to check CavWMON running on the server side. Authentication should be correct and password must be encrypted form Need that all configuration correct and connectivity with port. |
| Possible Reasons #2 | In CavWmon logs, logs are updating for TRNo. or not
In cmon trace log file, monitors request are there or not |
| Steps to Diagnose | “check sever side logs . check through nsu_server_admin command data is coming or not” |
| Commands to validate | “neu_validate_db_data -n 1211 -p 2020xxxxxx -o ns -l where n=> TRNO. and p => partitionpath: NS_WDIR/TRNo./Partition/ns_logs/ns_db_upload.copytrace to check errors for which tables related errors are coming.nsu_server_admin -s 10.10.220.2 -M “”mssql: -h 10.10.220.2 -p 1433 -A 0 -U hmisnr\\esdsadmin -P bmc@123 -t locks_stats”” |
