Re: Vmware Log Insight Keygen Software
Rosaura Woolf
VMware Aria Business Insights is an intelligent event management capability that leverages AI/ML to automatically organize symptoms across apps and infrastructure and determine actionable business insights. Where previously IT operations users had access to events in a siloed, isolated sense, challenges exist with sorting through the noise and determining what is relevant and what is not. VMware Aria Business Insights exists to provide context, to pick out the signal from the noise in real-time, and use that signal to remediate issues across the stack before they occur. It can discern relevant business insights from full-stack event correlation leveraging AI/ML analytics to eliminate business downtimes, reduce MTTR, and prevent future issues.
While the VMware Cloud Management portfolio has handled full-stack event monitoring and alerting, there is an opportunity for significant noise reduction by applying an AI/ML layer on top of the entire portfolio.
VMware Aria Business Insights operates within the observability philosophy required to optimize root cause analysis within complex distributed systems. It begins by correlating, clustering, and de-duplicating events across the stack, determining what to surface and what to suppress, and serving up relevant business insights to the user.
Remote logging is supported on NSX Manager, NSX Controller, NSX Edge, and hypervisors. It must be configured on each node individually. Be aware that, as previously stated, facilities local6 must be included in order to have relevant NSX log messages forwarded. Also, NSX log messages include a message ID field that allows to filter which messages are sent to a specific syslog server.
Before we start we first want to get something out of this world. When you configure the required Syslog commands on the NSX-T Manager the Manager will NOT push the logging servers to the Edge Transport Nodes or on the Transport Nodes. When we configure logging on the manager this will only provide information on what is happening on the manager.
In order to receive logging messages from our T0 and T1 Gateways, we also need to enable logging on the Edge Transport Nodes. We want to stress one more time that the logging server is NOT pushed automatically on the Edge Transport Nodes by the manager.
In order to log Distributed Firewall Rules (DFW) you need to enable commands on the Host Transport nodes (ESXi hosts) itself. You don't need any logging configuration on the NSX-T Manager and we tested this by removing the commands on the manager:
The facility, messageid, and structured-data fields are optional and for filtering logs. All NSX logs uses facility local6, and supported message id and structured data keys are defined in LogMessageId.java and NsxStructuredData.java
To use TLS and/or LI-TLS protocol, certificate file(s) are required. For TLS, two CA certificates along with a pair of certificate and private key for the NSX appliance need to be specified. For LI-TLS, a CA certificate need to be specified.
Using XCA, you need to create at least one CA certificate and two leaf certificates for the NSX appliance and remote syslog server, respectively. The created certificate and key files can be placed under /image/vmware/nsx/file-store for easy access from the NSX CLI. For example:
A dashboard is called a "tab" and a widget within that dashboard is called a "chart". Within each tab definition, there is a list of charts. Within each chart defnition, the feature teams need to specify the name, description, type, width, and query of the chart. Below is an example:
Here we created a dashboard called "NSX - Infrastructure". Within this dashboard we created a widget called "NSX Manager : Communication Errors". The chart_type field is for LI content pack and currently we support three types: stacked_column, table, and count. The value 50 for char_width_splunk means this widget will take 50% of the Splunk web page width. Similarly the value 1/2 for chart_width_li means the widget will take half of the LI web page width. The hard part is to figure out the Splunk and LI queries. Typically, you will need to have access to a Splunk server and an LI server. For Splunk, simply make sure the query runs correctly (i.e. returns the desired result). For LI, you need to create a custom widget under "My Dashboards" and then export the widget to obtain the query. An easy way is to clone an existing widget and then modify it.
No matter which mode chosen MP or Policy, you will not lose any data in Splunk, all will show up in Splunk but the current NSX plugin for Splunk only works on MP structure. The next version of plugin will support Policy.
If you wanna inist to use Policy mode, you can create a custom plugin which is fairly easy to do so with the right structure but it will not show in our NSX plugin tab in Splunk- gonna be only on the custom tab.
The self-signed certificate generates security warnings when you connect to Splunk or Log Insight web user interface. If you do not want to use a self-signed security certificate, you can install a custom SSL certificate. The only feature requiring a custom SSL certificate is Event Forwarding through SSL.
Port Connection Tool and Traceflow are two great tools for troubleshooting communication between workloads running in NSX. They show real-time information of the topology and detected issues (if any), thus reducing the time it takes to find out what is preventing such communication.
It shows a visual map with layers that display realized state data such workload information, Logical Port status and Tunnel-health status, representing hop by hop connectivity between various points in the path.
Traceflow takes troubleshooting a step further by injecting a packet at the logical port of the source workload, and displaying the step-by-step path such a packet takes until it reaches the destination workload. Admins can specify multiple characteristics of the packet to be injected, so that it matches their troubleshooting needs.
The trace packet traverses the logical switch overlay, but is not visible to interfaces attached to the logical switch, meaning, no packet is actually delivered to the intended recipients. Traceflow output includes a table listing Observation Type (Delivered, Dropped, Received, Forwarded), Transport Node, and Component, and the Port Connection Tool graphical map of the topology if unicast and logical switch as a destination are selected.
When there are connectivity issues, the table of observations and the visual output may provide different information. In the example below, the diagram shows the physical and logical port connectivity between the source and destination workloads while Traceflow observations report that the packet being injected is being dropped by the distributed firewall rule ID 1031.
IPFIX stands for IP Flow Information eXport, where in turn, IP stands for Internet Protocol. It is a standard protocol for the format and export of network flow information, which is collected by a remote IPFIX collector, that will typically display the information in an easy-to-understand way.
When IPFIX is enabled in NSX, all configured host transport nodes will send IPFIX messages to the collectors using port 4739. For ESXi hosts, NSX automatically opens port 4739. For KVM hosts, NSX does not automatically open the port, so if the host firewall is enabled, admins must manually open port 4739.
We setup our discovery scanner to scan vcenter and then checked the box scan virtual guests. The scan looks like it is collecting vm guest information but only loads the vmware host information when it is done and no guest information. If we scan subnets we can get the information to import. Is there a way to setup our scan without using subnets and only scanning vcenter?
In our company, we scan through a range that include all the vmware hosts only, and consequently, Discovery collects your VMs. When we import the results into Insight, vmware hosts are included in "Host" object and the VMs are included in "Virtual Guest" object.
