How to create an SNMP collector.
About this task
To add an SNMP collector:
Procedure
- In the Logical view, right-click the DataChannel
x folder.
The pop-up menu lists the following
options:
- Add Collector SNMP - Creates an SNMP collector.
- Add Collector UBA - Creates a UBA collector.
- Add Collector BCOL - Creates a BCOL collector. This collector
type is used in custom technology packs. DataMart must be added to
the topology before a BCOL collector can be added.
Select Add Collector SNMP. The Configure
Collector window is displayed.
- Using the drop-down list of available hosts on the Configure
Collector window, select the computer that hosts the collector
. (for example, corinth)
- Accept the default collector number (for
example, 1).
The default collector number is seen
in the collector number property. However, you need not accept the
collector number. You can edit the collector number and port number
as per your requirement. The collector number ranges from 1-999 of
which 500 and 501 are restricted for other purpose. The port number
ranges from 3002 to 3999 and 3003 by default is the watched process.
- Repeat the steps from 2 to 4 for as many SNMP collectors
you want to add. Ensure that the collector number and port number
should be unique for all the SNMP Collectors.
- Click Finish.
The
maximum number of SNMP components (SNMP Collector and SNMP Spare)
on a host is 16.
The Topology Editor displays the new collector
under the DataChannel x folder in the Logical
view.
Note: The port number property is not editable in the Topology
Editor once it is selected in the Configure Collector Window.
If you want to change the port number, you must remove the collector
from the topology by right-clicking on it and choosing remove.
Then add the collector back and edit the port in the Configure
Collector Window.
- Highlight the collector to view its properties. The Topology
Editor displays both the SNMP collector core parameters and the SNMP
technology pack-specific parameters. The core parameters are configured
with all SNMP technology packs. You can specify an alternate installation
user for the SNMP collector by changing the values of the pv_user, pv_user_group and pv_user_password properties
in the Advanced Properties tab. Review the
values for the parameters to make sure they are valid.
Important: Irrespective of the number of collectors that you
add, the directory is created only on /opt/dataload.
Note: For
information about the core parameters, see Properties
Reference.
Results
The collector has two components:
- Complex Metric Engine x - Perform calculations on the collected
data.
- File Transfer Engine (FTE) x - Transfers files from the collector's
output directories and places them in the input directory of the CME.
The FTE writes data to the file /var/adm/wtmpx on
each system that hosts a collector. As part of routine maintenance,
check the size of this file to prevent it from growing too large.
Note: Your
Solaris version can be configured with strict access default settings
for secure environments. Strict FTP access settings might interfere
with automatic transfers between a DataChannel subchannel and the
DataLoad server. Check for FTP lockouts in /etc/ftpd/ftpusers,
and check for strict FTP rules in /etc/ftpd/ftpaccess.
Note: The
Topology Editor includes the channel and collector numbers in the
element names. For example, DataChannel 1 could have Collector SNMP
1.1, with Complex Metric Engine 1.1. and File Transfer Engine 1.1.
