VCF Load Balancer Insight: Overview

Version: 2026.1.2.1

This page is the technical reference for VCF Load Balancer Insight. Everything described here appears in Aria Operations once an adapter instance has been configured and a collection has completed. The supported F5 models are BIG-IP LTM and BIG-IP SSL; the object model is shared across vendors and models and carries no vendor names.

Dashboards

All dashboards are shipped inside the Management Pack, are placed in a dedicated folder named after the product, and are installed automatically with the adapter content. They are vendor-neutral: the same dashboards serve every supported load-balancer vendor, because they are built on the shared object model, not on vendor-specific keys.

Load Balancer Health

The Load Balancer Health dashboard is the entry point for the load balancing estate:

• Load Balancer Clusters: a resource list of the clusters with their member count and standby members.
• Load Balancer Devices: a resource list of the member devices, coloured by the health badge and showing availability.
• Load Balancer - Active Alert List: the active alert list scoped to the objects produced by VCF Load Balancer Insight.

Load Balancer Device Status

The Load Balancer Device Status dashboard shows the base layer of each polled device:

• Device Identity and State: a table of failover_state, hostname, software_version and device_type.
• Device Resource Usage: cpu_usage, memory_usage and disk_usage per device over time.
• Load Balancer Devices - Active Alert List: the alerts raised against the devices.

Load Balancer Pools

The Load Balancer Pools dashboard covers the traffic distribution layer:

• Load Balancer Pools: a table of pools with active_count, total_count, load balancing mode and availability_state.
• Load Balancer Virtual Servers: a table of virtual servers with pool, availability_state and current connections.
• Load Balancer Pools - Active Alert List: the alerts raised against pools and virtual servers.

Load Balancer Members and Nodes

The Load Balancer Members and Nodes dashboard shows the backend endpoints:

• Load Balancer Pool Members: a table of members with node_name, pool_name, port and availability_state.
• Load Balancer Nodes: a table of nodes with ip_address, state and availability_state.
• Load Balancer Members and Nodes - Active Alert List: the alerts raised against members and nodes.

Load Balancer Certificates

The Load Balancer Certificates dashboard is the certificate renewal view:

• SSL Certificates: a table of days_until_expiration, issuer, subject and expiration_string per certificate.
• Certificate Expiry: certificates sorted by days to expiry, ascending, so the nearest expiry is first.
• SSL Profiles (Certificate and Cipher Group): a table of LB Profiles showing the ssl group fields — ssl|certificate, ssl|cipher_group, ssl|min_tls_version and ssl|sni_default — populated on the F5 SSL model.
• Load Balancer Certificates - Active Alert List: the certificate-expiry alerts.

Custom Groups

Custom Group Name	Description
LB World	A single container group that aggregates every object produced by VCF Load Balancer Insight, across all vendors and all ten object kinds. Shared network category convention with the other Indevops network Management Packs.
LB Clusters	LB Device objects grouped by their parent LB Cluster. A backstop for the read-only case where /cm/device-group cannot be read and the cluster is synthesized.
LB Devices by Type	LB Devices filtered on the top-level device_type property: standalone or cluster member.
LB Devices by Vendor	LB Devices filtered on the top-level vendor property: F5 or Citrix.
LB Devices by Model	LB Devices filtered on the top-level model property: LTM or SSL. Used to separate the LTM and SSL F5 estates in one adapter kind.

Alerts

Object	Alert	Metric	Condition	Recommendation ID	Severity
LB Device	Device is unreachable	availability	<= 0	Recommendation-df-lb-device-unreachable	Critical
LB Cluster	Cluster failover occurred	status|failover_state	change active -> standby	Recommendation-df-lb-cluster-failover	Warning
LB Cluster	Standby member offline	cluster|standby_members	== member_count	Recommendation-df-lb-cluster-standby-offline	Critical
LB Virtual Server	Virtual Server is down	availability	<= 0	Recommendation-df-lb-virtualserver-down	Critical
LB Virtual Server	High concurrent connections	connections|current	warning > 80%, critical > 95% of the limit	Recommendation-ud-lb-virtualserver-connections	Warning / Critical
LB Pool	Pool is down / no active members	availability, members|active_count	active_count == 0; availability <= 0	Recommendation-df-lb-pool-down	Critical
LB Pool Member	Pool Member is down	status|availability_state	= offline	Recommendation-df-lb-poolmember-down	Warning
LB Node	Node is down	status|availability_state	= offline	Recommendation-df-lb-node-down	Warning
LB Device	Resource utilization is high	system|cpu_usage, system|memory_usage, system|disk_usage	warning > 80, critical > 90	Recommendation-ud-lb-device-resource	Warning / Critical
SSL Certificate	Certificate expires soon	validity|days_until_expiration	warning < 30, critical < 14	Recommendation-df-lb-cert-expiry	Warning / Critical

Every alert is symptom-based, attaches to the object's health badge and embeds its recommendation. The Recommendation IDs are the fixed ER #77666 values; a different prefix fails the import into VCF Operations 9.1. Thresholds 80/90 % and 30/14 days are proposals pending customer approval.

Collected objects

Relationships

The topology is rebuilt on every collection cycle. The hierarchy is:

• The adapter instance is the root of the hierarchy and the single API entry point. It parents the cluster.
• LB Cluster is the HA group or device group. It parents every LB Device.
• LB Device is one BIG-IP member. It parents the network ports, the virtual servers, the monitors and the SSL certificates.
• LB Virtual Server terminates client traffic. It parents the default LB Pool it forwards to.
• LB Pool is the backend group. It parents its LB Pool Members.
• LB Pool Member is a node plus port in a pool. It parents the LB Node it points at.
• A VMware VirtualMachine is an external parent of LB Device, joined on the management address.
• A phpIPAM IP Address is an external parent of LB Cluster, LB Device, LB Port and LB Virtual Server, matched on the bare management_ip and vip_address properties.

Relationships are never declared in the adapter schema; they are added at collection time and cleared and rebuilt each cycle, so a relationship removed at the source disappears downstream.

Top-level attributes (all kinds)

Every object kind carries these ungrouped attributes. They are the only keys external relations and cross-vendor filters may rely on.

Data Name	Type	Description
availability	metric	1 when the object was collected, 0 when it was expected but unreachable or down.
management_ip	property	Management address; present on LB Cluster, LB Device and LB Port. The phpIPAM adapter matches the bare key ^management_ip$, so it must stay ungrouped.
vendor	property	Producer, for example F5.
model	property	Product family: LTM or SSL for F5.
device_type	property	standalone or cluster member; present on LB Device.
vip_address	property	Bare VIP IP; present on LB Virtual Server. The phpIPAM adapter matches the bare key ^vip_address$, so it must stay ungrouped.

LB Cluster

LB Profile ssl group (F5 SSL model)

The ssl group carries the SSL-offload configuration of a client-ssl / server-ssl profile. Every attribute is optional: it is emitted only when the endpoint returned a value for that profile, so the group is empty on a plain LTM / TCP / HTTP profile — never a zero. The two namespaces differ in what they expose: a server-side profile has no client certificate and no SNI flags, so those attributes are simply absent from it.

ssl|certificate	property	Certificate reference (cert) the profile terminates, e.g. /Common/wildcard-pern-pl.crt. Not present on a server-side profile.
ssl|cipher_group	property	Named cipher group the profile uses, resolved to its full path when /ltm/cipher/group is readable (e.g. /Common/f5-default).
ssl|ciphers	property	Inline cipher string (ciphers), e.g. DEFAULT.
ssl|ssl_protocols	property	Protocol set returned by the endpoint.
ssl|min_tls_version	property	Lowest TLS version derived from the profile options, e.g. tls1.2.
ssl|max_tls_version	property	Highest TLS version derived from the profile options, e.g. tls1.3.
ssl|sni_default	property	SNI default flag, true / false. Not present on a server-side profile.
ssl|sni_require	property	SNI require flag, true / false. Not present on a server-side profile.
ssl|renegotiation	property	Renegotiation state, enabled / disabled.
