ThousandEyes offers Digital Experience Monitoring that integrates application performance monitoring within a broader network monitoring platform. It primarily focuses on connectivity monitoring and supports SaaS and hybrid systems monitoring.
At least for me, it is a very important tool to diagnose bandwidth / Routing issues. Any global company should have ThousandEyes, it will avoid you many headaches. You'll need to invest in servers (on-prem and remote) in all locations in which you need, you can take advantage of all the monitoring tools.
Alerting on outages. ThousandEyes provides a few different options to receive alerts: you can have alerts emailed to a subset of (or all) users, there is a basic Slack integration, and if more flexibility is required (or your preferred method of being alerted isn't built-in) webhooks can be used to hit another API.
Speeding up mean time to resolution (or mean time to innocence if you're a more siloed and blame-happy organization). Failure alerts can be configured to include the cause of the failure instead of just "resource x is down." For example, the alerts can come out and say that a website was down due to an HTTP 500, which will help prevent staff from spinning their wheels trying to diagnose the network from the client to the web server.
Post mortems and root cause analyses. After an outage has been resolved, it is possible to go back for up to 30 days without losing any level of detail for the test in question, and to view information like the DNS response received, the network path taken by the traffic, and any added latency incurred by an individual link. It can also be used to view Internet routing changes surrounding the incident.
Support. Every ticket or chat I have opened has been met by a friendly and helpful staff member that has been able to provide helpful insight into what is causing a particular issue, and what steps they will take on their side to resolve an issue or provide suggestions of steps to take on our side if necessary.
Continue to innovate and support more and more services. In the world of IOT and point to point traffic being more and more prevalent creating a flexible product is fantastic. Build on the end user product, last mile and even more sharing.
We will definitely renew and maybe even extend our usage of ThousandEyes. We have been using ThousandEyes now for a couple of years and it has shown us major benefits. With the new options it offers for SD-WAN for us it is a no brainer to renew our current licenses
Sensu's customer support was always willing to work with us but never really seemed to learn much from our experiences. I think they get a lot of customers with DevOps IT teams that are willing to put in a lot of elbow grease to get the most of Sensu's architecture. However, despite explaining my continued disappointment with their documentation and the overall flow of the product, I never got much more than a "sorry" and a notice that their documentation was open source if I wanted to contribute to it. The problem, of course, is that you can't document what you don't understand. I'm a former technical writer, so I know that better than most.
You have online support from the tool itself 24/7 and they are very responsive. We also have a specific account manager and specific engineer assigned to help us with very specific questions for our environment. The level of response to our requirements is always super high. We have requested specific features to be added and these have been developed and introduced very quick tot he product (within weeks). Their DevOps and agile approach seems to pay off.
Have used New Relic and Sematext Cloud for APM and for tracking over days and visualizing the issues. But those are very expensive as compared to Sensu.
Simple Network Management Protocol cannot achieve what an agent-based monitoring solution can. Access layer testing gives you visibility into the user's endpoint. ThousandEyes is able to provide both telemetry and user experience in a bundled solution. The way that Cisco has built in the enterprise agents to their 9300 and 9500 switches has made exposure to the platform widespread.
Standing up the Sensu Go server took very little effort.
Setting up and maintaining the build processes and deployment logic for Sensu assets and checks was somewhat exhausting and resulted in lower adoption among non-DevOps IT.
The limited web interface resulted in lower adoption among non-DevOps IT.
