Note

The VMID Analytics feature is currently in beta status for use in non-production environment only. Contact your account teams or Cisco MDS marketing team to understand the use case before enabling this feature. This beta status and restriction will change to regular production status in an upcoming release.

The SAN Analytics feature provides Fibre Channel traffic information at a device (per FCID) level. However, end devices can host multiple virtual entities (virtual machines [VMs]) and each VM can cause a varying load on the Fibre Channel fabric. Therefore, it becomes crucial to monitor the Fibre Channel performance of each VM. The VMID Analytics feature can be used to monitor, analyze, identify, and troubleshoot Fibre Channel performance issues at a VM level.

Individual VMs within a given device use the same FCID for their SCSI and NVMe IO exchanges. The NX-OS Virtual Machine Identifier (VMID) server feature enables resolving traffic sources from a per-FCID device level to an individual VM level. For more information on this feature, see the "VMID" section in the "Managing FLOGI, Name Server, FDMI, and RSCN Databases" chapter of the Cisco MDS 9000 Series Fabric Configuration Guide, Release 8.x.

After the VMID server feature is enabled, the VMID Analytics feature can subsequently be enabled to resolve performance metrics for initiators. When enabled, analytics views that used to report the initiator level metrics will also report VMID level metrics. Only the view types which include the scsi-initiator-id or nvme-initiator-id key are monitored. An additional vmid key is supported for these view types. You must specify the vmid key as part of the "selected fields" list along with the initiator ID in the query syntax to collect the VMID-specific analytics. If VMID is not specified in the "selected fields" list and only the initiator ID is specified then the aggregated metrics are collected for the initiator.

Disabling the VMID Server feature cause attached devices to stop inserting VMID information into Fibre Channel frames. Also, when the VMID Analytics feature is disabled the frames are counted against the source FCID and not the VMID. However, the Analytics database continues to retain the previously collected per-VMID metrics. You must purge the metrics or perform a nondisruptive module upgrade to reset the database. If you do not purge the metrics, then the output of the pull or push query with and without using the differential option will be as follows:

• When you use the differential option in a pull or push query after the VMID Analytics feature is disabled, only the first pull or push query will contain the stale per-VMID metrics.

• When you do not use the differential option in a pull or push query after the VMID Analytics feature is disabled, every pull or push query will fetch the stale per-VMID metrics.

The VMID Analytics feature was introduced in Cisco MDS NX-OS Release 8.5(1).

The Port Sampling feature that is introduced in Cisco MDS NX-OS Release 8.3(1) allows you to gather data from a subset of ports in a module that is already being monitored, cycle through the various subsets of ports, and stream data from these ports at a regular port-sampling interval.

This feature is useful when the NPU load is high and you cannot reduce the number of ports that are being monitored on a module. In such a situation, the load on the NPU can be reduced by sampling a subset of the monitored ports at a specified port-sampling interval. Use the show analytics system-load command to check the NPU load.

In Cisco MDS NX-OS Release 8.3(2), system messages were introduced to alert you if the NPU load is high when the ITL count exceeds a module limit, when the ITL count exceeds the system limit, and when there is no response from NPU for analytics data. For more information, see the Cisco MDS 9000 Family and Nexus 7000 Series NX-OS System Messages Reference document.

Any I/O and errors that occur on a monitored port, when it is not being sampled, are not seen and not included in the analytics data.

The port sampling interval that is used in this feature is independent of the streaming sample interval. We recommend that you set the streaming-sample interval, port-sampling interval, and push query interval to be equal to or more than the minimum recommended value of 30 seconds.

Note	When this feature is enabled on a module and then the SAN Analytics feature is enabled on new ports on the module, the port-sampling data for the new ports are streamed only after the next port-sampling interval.

Port-Sampling Scenarios

Let us consider a module consisting of 48 ports and group them into two subsets of 24 ports. Depending on the port-sampling intervals that are configured for these subsets of ports and the streaming-sample interval that is configured, flow metrics can be captured at different intervals as seen in the following examples:

• When the port-sampling interval and the streaming-sample interval start at the same time:

  

• When the port-sampling interval and the streaming-sample interval start at a different time:

  

Depending on where the switches that support the SAN Analytics feature are deployed in a SAN fabric, the following deployment modes are possible:

Host Edge Deployment Mode

The SAN Analytics feature is enabled on all Cisco MDS core switches and on interfaces that are connected to hosts.

Storage Edge Deployment Mode

The SAN Analytics feature is enabled on all the Cisco MDS core switches and on the interfaces that are connected to storage arrays.

ISL Deployment Mode

The SAN Analytics feature is enabled on all the Cisco MDS switches and on the interfaces that are on any one side of ISLs.

The following image shows the functionality of the SAN Analytics feature when supported and unsupported modules (16-Gbps Fibre Channel, Cisco MDS 9700 40-Gbps 24-Port FCoE Module (DS-X9824-960K9), Cisco MDS 24/10-Port SAN Extension Module (DS-X9334-K9), and so on) are used in SAN.

Note	The numbers 1 and 2 in the Functionality of the SAN Analytics Feature When Supported and Unsupported Modules are Used represent two different flows from initiators to targets respectively.

Note

In the above ISL mode scenarios, the request responses can be seen on different members of port channel. When supported and unsupported modules are used on ISL, the analytics data that is analyzed on the ISL may not be accurate. Hence, we recommend that you do not analyze data on ISL where supported and unsupported modules are used.

This example shows how to enable the SAN Analytics feature on a switch:

A schema is used to display the data of interest that is stored in a database to a user. Use the show analytics schema command for more information on schema. Metrics are maintained in a database in the form of various view instances. These view instances can be retrieved using queries. See Views for more information.

The following is the query syntax that is used in the pull query, push query, clearing metrics, and purging views:

select all | column1[, column2, column3, …] from analytics_type.view_type [where filter_list1 [and filter_list2 …]] [sort column [asc | desc]] [limit number]

The following are the elements of the query syntax:

• analytics_type —Specifies the analytics type. Only the fc-scsi type is supported in Cisco MDS NX-OS Release 8.2(1) and Cisco MDS NX-OS Release 8.3(1). From Cisco MDS NX-OS Release 8.4(1), fc-nvme analytics type is supported.

• view_type —Specifies the view type of a metric database. The syntax is used to run queries on it. The syntax supports only one query on a single view type. For the list of supported view types and their descriptions, see List of Supported View Types.

• column —Specifies the flow metrics. A view instance contains multiple columns.

• filter_list —Specifies the filters to extract specific metrics of a view instance. You can use the filter conditions on a flow metric column whose type is a key value or on a view instance column. You can also use the AND operator for filtering. For a list of view types that are supported, see List of Supported View Types.

• sort —Specifies to sort the results in a column. Sorting is performed before the limit operation is performed.

• asc —Sorts the results in a column in ascending order. By default, sorting is done in ascending order if no order is specified.

• desc —Sorts the results in a column in descending order.

• limit —Limits the number of metrics that are returned in a result.

For examples on configuring query syntax, see the Examples: Configuring Query Syntax.

Note

The limit and where options in the "query_string" can only be used on the key fields. Prior to Cisco MDS NX-OS, Release 8.3(2), the sort option in the "query_string" could only be used on the key fields and the metrics were sorted only in ascending order. From Cisco MDS NX-OS, Release 8.3(2), the sort option in the "query_string" can be used on all the metrics and metadata fields and can be sorted in ascending or descending order using the asc or desc options respectively. By default, sorting is performed in ascending order if no order is specified. If you have configured push queries with the sort asc or sort desc option, make sure that you remove these sort options before downgrading from Cisco MDS NX-OS, Release 8.3(2) to Cisco MDS NX-OS, Release 8.3(1) or earlier releases.

The following are the rules for constructing queries:

• The select , from , where , sort , and limit conditions should be used in the same order as described in Query Syntax.

• The list of columns under the select condition should belong to the schema that corresponds to the view_type under the from condition.

• The where condition is allowed only on flow metric fields whose type is a key value. For information about the flow metric fields whose type is a key value, see List of Supported View Types.

• Before Cisco MDS NX-OS, Release 8.3(2), the sort condition must be a metric field and should be present among the columns that are listed under the select condition. From Cisco MDS NX-OS, Release 8.3(2), the sort condition must be a metric or metadata field and should be present among the columns that are listed under the select condition.

A view is a representation of the flow metrics about a port, initiator, target, LUN, or any valid combination of these. Each view type supports specific flow metrics. To optimize resource utilization, long names in the flow metrics are used for OnBoard queries and short names are used for SAN Telemetry Streaming. For more information, see Flow Metrics.

The show analytics query 'select all from fc-scsi.scsi_initiator' command provides an output of the flow metrics of all the initiators, as seen in the sample database shown in the following image:

The show analytics query 'select total_read_io_count from fc-scsi.scsi_initiator' command provides an output of a target’s total_read_io_count flow metrics, as seen in the sample database in the following image:

The show analytics query 'select total_read_io_count,total_write_io_count from fc-scsi.scsi_target_it_flow’ command provides an output of an initiator’s and a target’s total_read_io_count and total_write_io_count flow metrics viewed from the target, as seen in the sample database in the following image:

The show analytics query 'select all from fc-scsi.port where port=fc1/1 and vsan=2 limit 1’ command provides an output of a port’s flow metrics that are a part of port fc1/1, VSAN 2, with the number of records is limited to one, as seen in the sample database in the following image:

The show analytics query 'select all from fc-scsi.scsi_initiator where port=fc1/1 and vsan=3 sort total_write_io_count’ command provides an output of an initiator’s total_write_io_count flow metrics that are a part of port fc1/1 and VSAN 3, and the output is sorted, as seen in the sample database in the following image:

To display the installed push queries, run this command:

switch# show analytics query { all | name query_name}

To display the results of a push query, run this command:

switch# show analytics query name query_name result

To execute a pull query, run this command:

switch# show analytics query “query_string” [clear] [differential]

Note	Use the "query_string" to specify query semantics, such as select, table, limit, and so on, for example, “select all from fc-scsi.port”.

To reset all the flow metrics for a view instance that match the query string, run this command:

switch# clear analytics query “query_string”

Note

The "query_string" must have the format "select all from <view-name>". You can clear the flow metrics without installing a push query. The clear analytics query command is different from the clear option that is used in a push query. The clear analytics query command resets all the metrics that meet the query syntax and the clear option that is used in a push query resets the minimum, maximum, and peak flow metrics.

To delete a specific view instance and its associated metrics, run this command:

switch# purge analytics query “query_string”

Note	The "query_string" must have the format "select all from <view-name>". You can clear the flow metrics without installing a push query. The where clause in the purge query can accept only the port key field.

The flow metrics that are displayed using the show analytics query name query_name result command are the refreshed metrics at the time interval when this command was executed. For example, if a push query is configured to refresh at an interval of every 30 seconds, and the show analytics query name query_name result command is executed after 35 seconds, the push query displays the flow metrics that were refreshed when the time interval was 30 seconds.

To display the flow metrics of a configured push query, run this command:

switch# show analytics query name query_name result

Note	The number after “values” in the output indicates the corresponding number of a record. New metrics are added in Cisco MDS NX-OS Release 8.3(1) because of which the query results may vary slightly between Cisco MDS NX-OS Release 8.3(1) and later releases and Cisco MDS NX-OS Release 8.2(1).

This example shows the output of all the flow metrics of the SCSI initiator ITL flow view instance:

Note

Evaluating NPU load takes some time. If the connection to the switch is lost during the evaluation process, the process continues to run in the background until completion and the output is saved in a file. A syslog message is generated after the process is complete with the filename and the location of the file where the output is saved.

This example shows how to duplicate the output to a file named output.txt on bootflash:

Note	You can use the --outfile option with all the ShowAnalytics command options to duplicate the command output to a file.
