You may see the wrong statistics in the Health & Wellness interface if:
Some or all the hosts and services are not provisioned and enabled correctly.
You have a mixed-version deployment (that is, hosts updated to different
NetWitness
versions).
Supporting services are not running.
This section provides troubleshooting information for issues identified by messages

Solution
Restart the RabbitMQ, SMS, and
NetWitness
services using the following commands.
systemctl restart rabbitmq-server
systemctl restart rsa-sms
systemctl restart jetty
Solution
Run the following commands on
NetWitness Server
to make sure all these services are running.
[root@nwserver ~]# systemctl status rsa-sms
RSA NetWitness SMS :: Server is not running.
[root@nwserver ~]# systemctl start rsa-sms
Starting RSA NetWitness SMS :: Server...
[root@nwserver ~]# systemctl status rsa-sms
RSA NetWitness SMS :: Server is running (5687).
[root@nwserver ~]# systemctl status mongod
mongod (pid 2779) is running...
systemctl status rabbitmq-server
Status of node nw@localhost ...
[{pid,2501},
{running_applications,
[{rabbitmq_federation_management,"RabbitMQ Federation Management",
"3.3.4"},
Possible Cause
System Management Service (SMS), RabbitMQ, or Mongo service is not running.
Solution 1
Run the following commands on
NetWitness Server
to make sure all these services are running.
[root@nwserver ~]# systemctl status rsa-sms
RSA NetWitness SMS :: Server is not running.
[root@nwserver ~]# systemctl start rsa-sms
Starting RSA NetWitness SMS :: Server...
[root@nwserver ~]# systemctl status rsa-sms
RSA NetWitness SMS :: Server is running (5687).
[root@nwserver ~]# systemctl status mongod
mongod (pid 2779) is running...
systemctl status rabbitmq-server
Status of node nw@localhost ...
[{pid,2501},
{running_applications,
[{rabbitmq_federation_management,"RabbitMQ Federation Management",
"3.3.4"},
Solution 2
Make sure
/var/lib/rabbitmq
partition is less than 75% full
Solution 3
Check
NetWitness Server
log files (
var/lib/netwitness/uax/logs/nw.log
) for any errors.
Message/
Problem
ContextHub stops and does not allow you to add or edit data sources and lists.
Possible Cause
The storage is full by 95% or above.
Solution 1
Increase the storage by updating the YML file, located at /etc/netwitness/contexthub-server/ contexthub-server.yml.
For example, to increase storage from 120 to 150 GB, enter a value (in bytes) by editing the relevant parameter:
rsa.contexthub.data.disk-size: 161061273600
Solution 2
Delete unwanted or unused large list.
Solution 3
Configure the TTL index for the list to automatically delete STIX and TAXI data and to clean up storage space.
Message/
Problem
Context Hub runs on a fixed memory and 50% is reserved for cache. When cache is 100% full, the cache response stops. For all new lookups the response will be slow.
Possible Cause
The cache is full by 50% or above.
Solution 1
By default, Context Hub cleans the cache every 30 minutes. Reduce the cache expiration time of data sources.
Solution 2
Disable cache for data sources.
Solution 3
Increase the RAM of the CH Java process by editing the
-Xmx
option available in the /etc/netwitness/contexthub-server/contexthub-server.conf file. In
JAVA_OPTS
, search for the
-Xmx
option.
For example, edit the entry as follows:
-Xmx8G
where
8G
represents 8GB space. Then restart the ContextHub service.
Note:
The memory is less than the available system memory. Be aware that there are many other services running on the host.
Possible Cause 1
Unable to:
-
access the data source
-
parse or read a CSV file
-
schema mismatched CSV
Possible Cause 2
Unable to authenticate when accessing the data source.
Solution 1
Make sure to save the csv file at correct location i.e/var/lib/netwitness/contexthub-server/data/ and verify the required read permissions.
Solution 2
Make sure the csv file schema specified while configuring the data source matches. If not, then either create a new data source with the new schema or edit the csv file to match the schema. For example, if you configure a List Data Source with a schema with column1, column2, and column3. And next time you update the csv file where the number of column increase or decrease or the order of the columns are changed. In this case there is a schema mismatch and the configured list data source will show “Unhealthy” in Health and Wellness stats.
Solution 3
Make sure the password is correct. To confirm edit the data source, enter the password and click test connection.
For more information related the above solutions, see "Configure Lists as a Data Source" topic in the
Context Hub Configuration Guide
.
This section provides troubleshooting information for issues that are not identified by messages
NetWitness
displays in the Health & Wellness Interface or includes in the Health & Wellness log files. For example, you may see incorrect statistical information in the Interface.
Possible Cause
SMS service is not running. SMS service must be running on the
NetWitness Server
.
Solution
Restart SMS service.
Problem
NetWitness
does not show the version to which you upgraded until you restart jettysrv (jeTTy server).
Possible Cause
When
NetWitness
checks a connection, it polls a service every 30 seconds to see if it is active. During that 30 seconds, if the service comes back up, it will not get the new version.
Solution
Manually stop the service.
Wait until you see that it is it offline.
Restart the service.
NetWitness
displays the correct version
.
Possible Cause
After you upgrade to
NetWitness
version 10.5, JDK 1.8 is not default version and this causes the jettysrv (jeTTy server) to fail to start. Without the jeTTy server, the
NetWitness
server cannot display the
Service Unavailable
page.
Solution
Restart jettysrv.
