EMC Isilon Add-on for Splunk Enterprise

Overview
Details
This technology add-on collects data from Isilon to be used by the EMC Isilon App for Splunk Enterprise.

REQUIREMENTS


  • Splunk version 6.2,6.3 or 6.4.
  • Isilon running OneFS version 7.1.x or above.
  • If using a forwarder, it must be a Heavy Forwarder( because the universal forwarder does not include python).
  • Splunk forwarder system should have 4 GB of RAM and a quad-core CPU to run this app smoothly.
  • The forwarder system must have network access (HTTP/HTTPs) to Isilon system which is to be splunked.
  • Appropriate user credentials to collect data from Isilon node(Need to provide any one node ip from the Isilon cluster)
  • Admin user ID and password for collecting data from Isilon node.

HOW TO INSTALL

  • Add-On app can be installed through UI using "Manage Apps" or extract zip file directly into /opt/splunk/etc/apps/ folder.

HOW TO CONFIGURE

  • After installation, go to the Apps->Manage Apps->Set up TA_EMC-Isilon.New set up screen will open which will ask for Isilon node credentials. Provide ip address, username, password for any one Isilon node of your cluster and save them.(Please do not provide smart connector ip on setup screen. This TA expects actual ip of one of the node of Cluster)
  • Splunk REST API will encrypt the password and store it in Add-on's folder itself in encrypted form, REST modular script will fetch these credentials through REST API to connect to the Isilon node.
  • Restart the Splunk
  • To enable forwarding syslog data from Isilon cluster, perform the following step:
    1. Make following changes in file /etc/mcp/override/syslog.conf on Isilon node (copy from /etc/mcp/default/syslog.conf if not present) :
      • Put @<forwarders_ip_address> in front of the required log file and !* at the end of the syslog.conf file.
      • Restart syslogd using this command - /etc/rc.d/syslogd restart.
      • In some cases, syslog.conf file is already placed at /etc/mcp/override directory location but it is empty. In that case just put the log file name and the forwarder ip in that file.
      • Below is the cotent of sample syslog.conf:

      auth. @<forwarders_ip_address>
            !audit_conf
      . @<forwarders_ip_address>
            !audit_protocol
      . @<forwarders_ip_address>
            !

    2. Run the following commands to enable syslog forwarding according to Isilon OneFS version:
      • For EMC Isilon cluster with oneFS version 7.x.x -
      • isi audit settings modify --config-auditing-enabled=yes        isi audit settings modify --config-syslog-enabled=yes
      • For EMC Isilon cluster with oneFS version 8.x.x -
      • isi audit settings global modify --config-auditing-enabled=yes        isi audit settings global modify --config-syslog-enabled=yes
    3. Enable receiving the syslog data at forwarder. To do that, go to Settings -> Data Inputs -> UDP -> New. Provide port number(514 is recommended by Splunk), sourcetype as emc:isilon:syslog and index isilon to this data input entry.
    4. Make sure while receiving syslogs on you have set following metadata - index=isilon, sourcetype=emc:isilon:syslog.

CIM Compatiblity

This app is compatible with "Authentication","Inventory" and "Performance" datamodels of Splunk CIM (Comman information model).

TEST INSTALLATION

The main app dashboard can take some time to populate the dashboards once data collection is started. A good test to see that you are receiving all of the data we expect is to run this search after several minutes:

search `isilon_index` | stats count by sourcetype

In particular, you should see these sourcetypes:
* emc:isilon:rest
* emc:isilon:syslog

If you don't see these sourcetypes, then

• For emc:isilon:rest, have a look at the messages for "emc:isilon:rest" . Here is a sample search that will show them:

index=_internal component="ExecProcessor" "EMC Isilon Error:" | table _time host log_level message

• For "emc:isilon:syslog", check the syslog file in /etc/mcp/override/syslog.conf - it should have @<forwarders_ip_address> in front of the required log file and !* at the end of the syslog.conf file. Also run following command to see whether the syslog forwarding in enabled or not:

For EMC Isilon cluster with oneFS version 7.x.x - isi audit settings view
For EMC Isilon cluster with oneFS version 8.x.x - isi audit settings global view

EMC Isilon forward syslog and audit logs on 514 udp port by default. Please make sure port 514 is open and reserver for Isilon syslogs only.
