How the new Apica® and PathSolutions® partnership helps IT teams connect application failures to what's actually happening on the network.
When an application slows down or a transaction fails, the network is often one of the first suspects. The application team sees the problem, the network team checks its monitoring tools, and the investigation begins.
But what happens when the network dashboards look healthy?
The problem may still be in the network. A marginal cable, an interface error, a VLAN tagging issue, or a configuration change can affect application performance without triggering the alerts engineers typically rely on. And when application and network teams are working from separate sets of data, finding the connection between a failed transaction and its underlying cause can take longer than it should.
That's the problem PathSolutions can now address directly through a new technology partnership with Apica.
Watch the video: Andi Mann, Chief Product and Technology Officer at Apica, and Tim Titus, Founder and CTO of PathSolutions, discuss the partnership.
By integrating Apica Vanguard synthetic monitoring with PathSolutions TotalView® network root-cause analysis, we're bringing application-level detection and detailed network diagnostics together. When a transaction fails, teams can see not only what went wrong from the application's perspective, but whether the network contributed to the problem and why.
Apica Vanguard continuously tests applications and services from global vantage points, monitoring everything from multi-step transactions and APIs to authentication processes and AI agent workflows. These synthetic checks help organizations identify failures and performance issues, often before users report them.
TotalView approaches the problem from the network side. It collects and correlates detailed operational information from switches, routers, firewalls, and other network devices, including interface error counters, configuration data, traffic conditions, and performance metrics.
Where conventional network monitoring might indicate that a device is operating normally, TotalView's diagnostic heuristics can identify underlying conditions that explain why users are still experiencing problems.
The new integration connects those two perspectives.
When Vanguard detects a failed or slow transaction, it identifies the source and destination IP addresses associated with that activity and directs TotalView to inspect the specific network path involved. TotalView analyzes the relevant network conditions and returns a plain-English diagnosis, including recommended corrective action when a problem is identified.
That diagnosis is then combined with Vanguard's application findings in a single incident, which can be routed through existing IT service management and incident response tools, including ServiceNow and PagerDuty.
Instead of beginning with separate investigations, teams have application and network findings available together.
The process follows five steps:
Because the network analysis is triggered when a check fails, the integration doesn't require continuous additional polling. TotalView also performs its analysis on-premises, sharing the diagnosis rather than sending raw network telemetry through the integration.
One of the biggest challenges in network troubleshooting isn't necessarily identifying that something is wrong. It's determining which system or component is responsible.
When application monitoring and network monitoring operate independently, teams often spend valuable time collecting evidence, comparing timestamps, and trying to reproduce conditions that may have already disappeared.
The Apica and PathSolutions integration helps eliminate much of that preliminary investigation across IT:
Just as importantly, the integration helps organizations rule out the network when it isn't responsible. Knowing where not to troubleshoot can be nearly as valuable as identifying the root cause.
The partnership doesn't require organizations to replace their existing monitoring investments.
Apica Vanguard continues to provide application-level synthetic monitoring, while TotalView delivers the detailed network intelligence needed to diagnose infrastructure-related problems. Each platform retains its own capabilities and workflows, with the integration connecting their findings when an issue occurs.
This is particularly useful as enterprise environments become more complex and applications increasingly depend on distributed services, APIs, and automated workflows. Whether a failed transaction involves a traditional business application or an AI agent calling an external service, understanding the network's role remains essential to troubleshooting.
At PathSolutions, we've always believed that collecting more complete network data is what makes faster, more accurate root-cause analysis possible. This partnership puts that intelligence to work in a broader operational context, connecting what an application experiences with what the network is actually doing.
The result is a more direct path from detecting a problem to understanding its cause—and getting it resolved.
Join PathSolutions founder and CTO Tim Titus and the Apica team on December 7, 2026, for a live webinar demonstrating how Vanguard and TotalView work together to connect application monitoring with network root-cause analysis.
See how the integration helps IT teams rule the network in or out, identify underlying problems, and move from detection to resolution with less guesswork.
