![]() ![]() Alternatively, you can send syslog to another DCN virtual machine dedicated to run as a syslog server for the ESXi hosts. In a larger production environment, use a central syslog server with a Splunk Universal Forwarder and Splunk_TA_esxilogs add-on installed on it. ![]() For an environment with fewer than 40 ESXi hosts, send syslog traffic to the DCN. Prior to ESXi version 6.x, ESXi versions supported either TCP or UDP, but not always both. Forward this data from the DCN to Splunk indexers. The DCN contains all of the components required to collect vCenter Server log data. If firewall issues prevent you from installing the Splunk App for VMware components on vCenter Server, forward the vCenter Server log data to the data collection node (DCN). To send log data from the vCenter Server system on port 9997, install the Splunk Universal Forwarder and the Splunk_TA_vcenter on the vCenter Server system. This table describes how the entities in your environment communicate. You can collect log data from the vCenter Server system and the ESXi hosts in your environment. The DCN retrieves the data from vCenter Server and forwards the data to the Splunk indexer on port 9997.Ĭollect log data from vCenter Server systems and ESXi hosts ![]() Splunk App for VMware sends information to the data collection nodes using port 8008 about the information they need to collect from a specific vCenter Server system. The DCN uses port 443 to determine the kind of data to collect, such as performance, inventory, or hierarchy data. Uses port 9997 to forward data it has retrieved from the vCenter Server using the API.Īfter Splunk App for VMware establishes a connection with vCenter Server, the DCN uses port 443 to obtain the credentials for vCenter Server. To change the ports for each data collection node individually, set the port in each stanza.Ĭommunicates with vCenter Server API on port 443 to execute the data collection tasks allocated to it. Data collection nodes do not have to communicate on the same port. In your environment, if another service uses port 8008, you can configure a different port for communication between the data collection node and the gateway. When the DCN and Splunk App for VMware have established a connection, the Collection Configuration dashboard, which typically runs on the search head, allocates data collection jobs to the DCN on the TCP port 8008 (gateway port). It uses this port to discover the number of managed ESXi hosts in the environment.Ĭonnects to the Data Collection Node (DCN) on the default Splunk management port, TCP 8089. Uses port 443 to connect to the vCenter Server to verify that the vCenter Server credentials are valid. This table lists the components that communicate with each other and the ports they use to communicate. The Splunk Add-on for VMware communicates with vCenter Server using network ports and Splunk management ports. The Splunk App for VMware relies on the Splunk Add-on for VMware to use the VMware API to collect data about your virtual environment. Please feel free to submit contributions to the App using pull requests on GitHub.Configure ports Collect data from vCenter Server systems using the VMware API Optionally, you can clone the GitHub repository to install the App. This App is available on SplunkBase and Github. If unsure, set the acceleration time period to 7 days.ĭatamodel acceleration is not required if using the Add-on only. The time period represents how much data will show in the dashboards, and has a significant impact on storage usage. Acceleration is on by default in App 6.0 and lower, and off by default in App 6.1 and higher (due to new Splunk app certification rules)Įnable it now by navigating to Settings -> Datamodels, then select each Palo Alto Networks datamodel and enable acceleration for a time period of your choice. If using the Palo Alto Networks App, you must enable datamodel acceleration to see data in the dashboards. Install the Palo Alto Networks App by downloading it from the App homepage, or by installing it from within Splunk. Dashboards will notĭisplay any data until the data model is accelerated. Data Model acceleration is no longer enabled by default. ![]()
