Frequently Asked Questions (FAQs)
B.1 Installation And Upgrade
Can I use a different TCP port for MySQL?
In order to change the port used by the aggregated database (MySQL), complete the installation of NetVigil and then:
- Stop NetVigil if it is already running using the controller on Windows or
NETVIGIL/etc/netvigil.initon Unix.- Edit
NETVIGIL_HOME/etc/mysql.confand change the port number specified by port=nnnn entries. There should be two such entries and you should specify the same value for both. On Windows platform this file will be namedmy.ini- Edit NETVIGIL/etc/netvigil.xml and locate the following section:
Change the value of the port parameter to the new port number entered in mysql.conf (or my.ini) above.
Change the value to the new port number entered in mysql.conf
What changes are required when the change the IP address of the BVE database server?
The DGEs need to know the IP address of the provisioning database to download their configuration. Furthermore, the JMS Messaging server also runs on this host and so its address must be updated on the DGEs.
On all the DGEs, edit NETVIGIL_HOME/etc/netvigil.xml file and update the following section:
as well as the JMS section:
On the host running the Provisioning Database, edit NETVIGIL/etc/openjms-mysql.xml and update the following section:
Then restart the NetVigil components on all the servers.
What changes are required when I change IP address of a DGE host?
When the IP address of the DGE host is changed, no configuration change is required on the DGE itself. However, the BVE needs to know the IP address of the DGEs in order to query them for the reporting data.
You will need to update the new IP address in the BVE. See Section 10.1.1, "Configuring a New DGE" on page 143
Can I run the Web Application on a different TCP port?
See Section 3.4.11, "Web server TCP/IP port" on page 37
How do I enable SSL support on the Web Application?
Since the NetVigil UI is pure HTML based, you can access it using http or https. See Section 3.5, "SSL Support on Web Application" on page 39 for more information on setting this up.
B.2 Using and Configuring NetVigil
How do I change significant digits in test result?
NetVigil only supports integer values for polled results, so the results are rounded off before they are stored in database. You would need to use the rate multiplier to get the number of relevant significant digits. For example, if you need to monitor values up to two significant digits for load average, modify the test and enter 100 as rate multiplier.
How do I load the Enterprise MIB from vendor X?
Strictly speaking, even if you "loaded" a MIB into NetVigil, the Web Application would not know which particular OIDs to automatically discover, what to name the different tests, what unit to use while displaying results, or the DGE would not know how to process various pieces of collected information (e.g. convert bytes transferred into utilization percentage or Kb/s). You would need to look at each OID in the MIB, evaluate it's usefulness, and if you decide to use it, you would need to instruct NetVigil on what post-processing (if any) needs to be performed.
You can always monitor any custom MIB by adding it in the "Advanced Tests". However, it is preferable that you send the enterprise MIB to Fidelia support team who will work with you to add it into the NetVigil auto-discovery library of devices. Once installed, the tests will automatically be discovered and monitored by NetVigil
Is there a way to tell NetVigil to use 64-bit SNMP counters?
NetVigil test discovery process will automatically search for, and prefer SNMP v2 64-bit counters over older 32-bit counters when available. However, the tool will only search for 64-bit counters when the device has been configured to be SNMP v2 capable.
SCO Unix SNMP agent does not provide information on disk/CPU utilization
See Section C.7, "SCO Unix" on page 377
How do I monitor a DB2 database?
See Section 6.5, "SQL Performance Monitor for Databases" on page 81
How do I monitor availability of a Windows service?
- Add a Windows device using
Manage -> Create Device. The windows device must be accessible using WMI.- On the list of test types to discover, make sure that WMI is selected.
- When you click on the Continue button, NetVigil will automatically display all the services running on the server. Select the ones that you would like to monitor.
- Click on Submit button to provision the device.
SQL Query test on Oracle fails with "ORA-00911: invalid character" error.
The Oracle database (JDBC) driver used by NetVigil automatically adds
';'at the end of the SQL query (e.g. select count(*) from table1) automatically. Check the query string provided to the test and make sure that it is not terminated with';'Frame Relay: how to set the value of the CIR
In a frame relay circuit, the maximum value of the router interface can be different from the actual CIR (Committed Information Rate) set by the telco. During auto-discovery, NetVigil might not be able to discover the CIR correctly. In such a case, just edit the test and set the Maximum value of the interface to match the CIR. You can edit the test by going to
Manage -> Devices -> Update Testsor by using the BVE API for bulk changes.B.2.1 Using the Web Application
NetVigil is installed and I am logged in as "netvigil". How do I create new accounts/users?
You will need to log in as a "superuser" or as a department administrator. See Section 8.1.1, "End-users and Departments" on page 107 and `user.create' under Section 23.2.1, "Client Commands" on page 291
B.2.2 Actions/Notifications
How do I send SNMP traps to another host?
You need to configure actions and notifications. See Section 17.2, "Managing Action Profiles" on page 231
B.3 Integration And Advanced Topics
How do I monitor for text patterns in a log file?
See Chapter 7, "Message Handler for Traps & Logs".
How can I move devices from one account to another?
