Introduction
Most of the network devices, such as firewalls, switches, routers, web proxies etc send the traffic and user activity related information in the form of logs over syslog protocol. Some applications such as Oracle database server, Symantec antivirus server, EMC SAN Storage etc also support syslog protocol as syslog is very efficient and simple to integrate with. KHIKA Data Aggregator is pre-configured with syslog services on port 514. The key parts to get here are :
- Enabling Syslog forwarding on the device
- Install the KHIKA App for Cisco Switch
- Get data from your Cisco Switch into KHIKA Aggregator
Enabling Syslog forwarding on the device
Please refer "Configuring the UNIX System Logging Facility" section in Cisco Switch Documentation for enabling syslogs on your cisco switch device.
Example of commands to be fired on Cisco Switch Device to enable syslogs:
1. logging <IP Address of khika aggregator>
2. logging trap debugging (7)
3. logging on
4. service timestamps log datetime localtime show-timezone msec year
5. ip inspect audit-trail
Commands to enable login/logout logs on Cisco switch.
1. login on-failure log every 1
2. login on-success log every 1
Verifying SYSLOG data collection
After you enable the syslog forwarding on the end device, you must verify if the logs are being really received by KHIKA Data Aggregator. Please refer here to understand how to verify syslogs on KHIKA Data Aggregator.
How to Install the KHIKA App for Cisco Switch?
It is assumed, that you have already configured KHIKA Data Aggregator in your environment. If not, please read how to configure KHIKA Data Aggregator and perform the pre-requisite steps.
This section explains how to pick and install the KHIKA application for Cisco Switch. Installing the application shall put together and activate the adapter (parser) that can handle Cisco Switch data format, the dashboards, and the alert rules preconfigured.
Go to the “Applications” tab in the “Configure” menu.
Check whether the appropriate Workspace is selected. Note: Application is always loaded in a Workspace. Read the section KHIKA Workspaces to know more about KHIKA Workspaces. Also select your KHIKA aggregator name in the Node dropdown. This is to ensure that we are collecting data from the desired source and into the correct workspace which is ready with the configured application and components.
Click on the “+” button. A pop up appears.
User can now select the contents of the application required. For example, on the dropdown for “Reports”, click to expand it. List of all reports can be seen. User can individually select the reports required by checking on the checkbox next to each. Alternatively, check on “Select All” option to get all of them. Similarly you can select contents from Alerts and Dashboards.
Visit the sections on KHIKA Reports, KHIKA Dashboards, KHIKA Alerts & Correlations to know more about these topics.
Click “OK” to proceed with the installation of the selected Application. After successful installation, following status should be displayed :
This simple procedure to install a KHIKA App, automatically configures the Adapter (required for parsing the data from raw syslogs), calculated KHIKA reports on raw data, Visualizations, Dashboards and Alerts – all in one click.
Adding the device in the Adaptor
After syslogs are enabled on the device and the App is installed into KHIKA, it is the time to add the device to the this App (in Adapter section of KHIKA Web GUI). Please refer here to know how to add the device to an App.
After making these configurations in KHIKA, you must apply these changes to the Workspace. Go to Configure, select the Workspace and in Workspace tab of configure menu press the Apply button as shown in the screenshot below.
Wait for a few minutes for changes to apply and data to arrive in kHIKA. With all these steps, we should now expect the data to arrive in KHIKA. Lets discover some live data in KHIKA.
How to check the output of Cisco Switch App ?
Discovering the logs of Cisco Switch
After doing all the steps given above, we should start receiving live data into KHIKA. Go to "Discover" section in KHIKA GUI and select the index with name "*raw-ciscosys*". Note that the index has a prefix of the customer name and workspace name. After selecting this index, you should see the live data coming in. Spend some time understanding this data and the fields of the data.

Cisco Switch Alerts
Alerts are generated when certain critical behavior is observed in the system. Alerts can be monitored in real-time on the Alerts Dashboard in KHIKA. Relevant stakeholders can also receive the alerts via emails. The table below explains all the pre-canned alerts shipped with KHIKA App for Cisco Switch.
Alerts Description
| Alert Name | Description | Suggested Resolution |
| Neighbor Down of a Switch | This alert is triggered when the event occurs such that a neighbor is in the down state. | This alert signifies that the neighbor relationship with the corresponding router/switch is down. This typically happens when Router/Switch does not receive keepalive/HELLO packets from the neighbor for a period of time longer than the Dead timer interval. If neighbor in the downstate, verify that the neighbor router is up, is running, and is properly configured for OSPF on the interface. You may refer the OEM Router/Switch manual for further information in this regard. |
| Command executed on switch | This alert is triggered when "cfglog_loggedcmd" message is available in the event. | Certain Commands have been executed on switch. You need to ensure that admin/configuration change commands are executed by authorized user only. |
| SLA Down on a Switch | This alert is triggered when the state changed Up to Down for SLA reachability | With Cisco IOS IP SLAs, service provider customers can measure and provide. service level agreements, and enterprise customers can verify service levels, verify outsourced service level agreements, and understand network performance. Cisco IOS IP SLAs can perform network assessments, verify quality of service (QoS), ease the deployment of new services, and assist with network troubleshooting. This alert denotes that network performance (as defined by SLAs) between multiple network locations or across multiple network paths is down/lower than expected SLAs. |
| Link down on switch | This alert is triggered when "changed state to down" message available in an event for a particular switch device. | Link down on switch Admin may refer switch manual to take required action. |
