Building Intelligent Operations: MCP, AI Agents, and Incident Automation
We’re excited to bring the community together for an evening of learning and connection. This time, we'll have a community member from PagerDuty sharing a use case and, as usual, an Elastic employee sharing their expertise as well.
Come support your fellow developers, learn something new, and meet others who are passionate about search, observability, and security.
**Date and Time:**
Monday, June 29th, from 5:30-7:30 pm EDT
**Location:**
Elastic Arlington Office - 4100 Fairfax Drive, Ste 500, Arlington, VA 22203
**Agenda:**
* 5:30 pm: Doors open; say hi, grab a seat, and eat some food.
* 6:00 pm: **Beyond the Alert: Scaling Incident Response with Elastic, PagerDuty, and MCP**, by Nick Worthington, Senior Solutions Consultant at PagerDuty
* 6:30 pm: Q&A with Nick
* 6:40 pm: **Observability AI Agents - Behind the Scenes,** by Josh Phifer, Principal Solutions Architect at Elastic
* 7:10 pm: Q&A with Josh
* 7:20-7:30 pm: Networking & refreshments
**Talk Abstracts:**
**Beyond the Alert: Scaling Incident Response with Elastic, PagerDuty, and MCP**
In this session, we will dive into the next generation of the Elastic and PagerDuty integration. Discover how to leverage Model Context Protocol (MCP) and advanced automation workflows to ingest telemetry, contextualize alerts, and trigger automated remediations. Learn how to reduce MTTR and eliminate alert fatigue, turning your incident management framework into a scalable operation.
****
**Observability AI Agents - Behind the Scenes**
In the age of AI, nearly every observability platform offers some form of intelligent assistance — from automated root cause analysis and incident triage to query generation and dashboard creation. Yet for most users, these AI agents remain black boxes: powerful, but opaque.
What principles guide their design? How do they reason over telemetry data? And what if you need to customize, extend, or build agents tailored to your organization’s workflows? In this talk, we’ll peel back the curtain on observability AI agents. We’ll explore the reasoning strategies, and orchestration tools that power them. Finally, we’ll dive into how Elastic’s AgentBuilder and Workflow ecosystem enable teams to move beyond out-of-the-box automation - empowering you to shape and build the agent experience your operations demand.

Yoga Therapy: Stretch, Destress & Restore
Hit the pause button for an hour and reduce your stress.

Photograph One A Day (31 Day July Project)
**The rules are simple:**
Take photographs **Each and Every Day,** and post your best **ONE** (1) shot of the day - **EACH DAY** for **July**. If you happen to miss a day or two (life happens), it is **OK** to catch up and upload the photos for the days missed, or just skip those days.
**Please don't post over 2 to 3 at a time**. This is part of the learning process.
**DO NOT POST TO THE ALBUM *UNTIL* AFTER 07/01/2026**.
Please use a browser like Chrome and the Meetup.com website to post the images, as **the Meetup app does not handle albums very well**.
Towards the top-left of the page is a link to **Add Photos** for uploading your photo to the album. **CONFIRM** **that your photo was added to the correct Album.** Remember to post your **best photo (JUST ONE)** you took every day on that day! **DO NOT POST PHOTOS FROM ANY OTHER TIME!** If you have time to post an older image, you can take a new image and post it. Be creative.
Please **add a caption** to know how far you are in the process. After you upload the image you took that day, find your photo at the end of the album, and edit the caption to state the day and total number of days in the month like this:**?/31**. You can add the title of the image if you wish. A good title can make a photo! So, your photo for the **July 1st** caption would be "**1/31: My great photo!**" \*\* Adding a caption helps you keep track of where you are in the month. It does help.
The purpose is to have fun and get in the habit of shooting every day. Learn to use your camera. Read your manual and test out a new feature you have never used before. Sometimes picking a theme/project can help focus (pun intended), like flowers, your pet(s), a lens you haven't used in a while, or whatever your passion is. Or try something new...
The **end date is 07/31/2026**. Meetup.com does not allow events to be longer than 2 weeks.
Other images that were not taken by you will be removed. Please keep the images family-friendly. You need to be a member of the Virginia Beltway Photography Group.
I look forward to seeing how far people go and grow as better photographers!
Photograph Kenilworth Aquatic Gardens July 4th
In previous years, the rangers said they try to get to the park and open the gate by 7:45 AM.
From the website:
[https://www.nps.gov/keaq/index.htm](https://www.nps.gov/keaq/index.htm)
Waterlilies are bountiful all over the park! Our volunteers moved the tropical lilies from the hothouses to the display ponds, and they are vibrant. Bird enthusiasts have been enjoying watching the 3 young fledgling red-shouldered hawks, nesting orchard orioles, and kingbirds. Turtles have been laying eggs, and tadpoles and frogs are abundant in the ponds.
Every year, we visit Kenilworth Aquatic Gardens on July 4th. The lotus flowers start blooming in early June and will be plentiful by the end of the month. The best time to visit is in the morning as the temperatures are cooler and the flowers close up in the heat of the day, usually around 1:30 pm.
I know it is outside of the Virginia Beltway, but it is not far. It is a very unique place in Washington, DC. I will be there in my red smart car and rain or shine (hopefully shine)!
Bring:
Tripod
Comfortable shoes
Water
Fully charged batteries
Empty memory cards
Rain poncho and plastic bags for the camera and lens in case of rain.
Share only your very best, most interesting shots after the field trip, and keep it down to between 5 and 10 photos.

Plus Code: W375+6W Washington, District of Columbia
Website: https://www.nps.gov/keaq/index.htm
I generally schedule this meetup on the Fourth of July, as I would have the day off. They are open on July 4th, but one year we waited until 9:00 AM until a ranger showed up to unlock the gate and it wasn’t a holiday. I also want to mention security as one year a photographer in my group was at the gardens and saw someone’s car being broken into in the parking lot.
From the parking lot, walk towards the gardens down the path. I usually stay to the left and head into the lotus fields. Please be careful, as there are just dirt paths between the fields, and if there has been a lot of rain, there can be ruts, and I almost twisted my ankle.
You actually need a fairly long lens as the Lotus flowers are tall and can be some distance away. A wide-angle is only good for some overall shots and a good-sized macro works as well. Another thing folks do not realize is that the flowers do bloom into September, but have many full blooms. This is one park where you do not have to worry about mosquitoes as they are eaten by pond beetles, dragonflies, and damselfly larvae, and also by frogs and birds.
There is a boardwalk at the back of the flower fields that goes out to a marsh area. I have seen many types of birds and dragonflies in that area. Being there makes it hard to believe that you are in Washington, DC.
On the way out, allow some time to check out the small ponds with different lotus and lilies that also attract frogs and dragonflies.
Why you will not see any mosquitoes in the park:

A Poetry Workshop
Hey Poetry Lovers!
This group is on a roll. Here’s the gist:
We meet at the **Capital One Café in Chinatown** from **12pm - 2pm** every other week.
For enrichment, we start by reading and reflecting on a **“published poem”**, suggested by someone in the group. No advance preparation is necessary. But feel free to check out some of the poems we’ve read [here](https://docs.google.com/spreadsheets/d/e/2PACX-1vSyE_wCLQCPHRrKmN5F9tOIeeRQUZESxjRXGVBoCF2uU8Gm0_d0uECiCBCQXEy6ksxfsBOhtRIOpW3T/pubhtml?gid=0&single=true&widget=true&headers=false%22%3E%3C/iframe%3E). Or submit suggestions for future meetings [here](https://docs.google.com/forms/d/e/1FAIpQLSexGc2Z2Kp6bZW0D3_hfJ7NUUkfNHf7TXX-43FglCeBd9EF2Q/viewform?usp=send_form).
Next, we **share our work and offer feedback**. Depending on attendance, everyone gets \~10 minutes to use as they like. (No need to share, though; you’re welcome to come even if you prefer just to listen.)
We maintain a **Discord server** to help share our work and communicate outside our bi-weekly meet-ups. If you haven’t used Discord before, take a moment to download it and create an account before arriving. When we meet you on Saturday, we will add you to our server, the “DC Poetry Workshop”, and can help you navigate the app if you have questions.
Finally, if you plan on sharing a poem, consider how you will do so. Some options include:
* Print 5-10 copies to distribute in person
* Take and share screenshots in the Discord chat.
* Copy the poem into a google doc, change sharing settings to “anyone with link”, and copy the google doc link into the Discord chat.
Most importantly, we’re excited to meet you!
Catch you on Saturday,

Open Bar & Seminar (Free but RSVP required)
After hosting successful events, I always think that we could have done better and relate it to our day to day life and make it educational. In this connection, I wanted to show off my investment and trade hat and organize series of Happy Hours around Investment & Trade.
We will have speakers from different sectors and industries, at each Happy Hour. At this particular event, the speakers will discuss retirement savings with an overview of annuities and how they can be used in retirement.
Topics will include:
* Today’s retirement savings challenges and approaches
* Sources of income in retirement
* Annuities and how they can be utilized for retirement savings and income
• RSVP is required.
The address will be sent to members who RSVPed, before the Event.
Enjoy!

Stop Guessing: How to Measure and Improve LLM Outputs
Most people use LLMs by feel: ask a question, read the answer, decide whether it “seems good,” and move on.
That works for casual use. It does not work when you are building software, automating workflows, writing important documents, or relying on AI for anything that needs to be repeatable.
In this talk, we’ll look at how to improve and evaluate the inputs and outputs of LLMs using practical measurement techniques. We’ll cover how prompt changes affect results, how to compare outputs, how to build simple evaluation sets, and how math-based methods like similarity scoring can help you move beyond guesswork.
This will be beginner-friendly, so even if you don't know anything about AI, you should get something out of it. However, this will be a little more technical than our intro talks. You do not need to be an AI researcher, but programmers and technically curious attendees will get a lot out of it.
We’ll cover:
* Why “it looks good” is not enough
* How to improve prompts by changing the input, context, and constraints
* How to compare LLM outputs more systematically
* Basic evaluation techniques for accuracy, consistency, and usefulness
* How embeddings, cosine similarity, and scoring can help evaluate results
* Where automated evaluation works — and where humans still need to stay in the loop
By the end, you’ll have a practical mental model for treating LLMs less like magic and more like systems you can test, measure, and improve.
LOGISTICS AND PARKING:
The talk starts at 7:00 PM. The first half hour is reserved for everyone to get set up and mingle. Free pizza and drinks!
The cheapest parking option is to find street parking, which will only cost you a few bucks. Otherwise, park in the nearby veteran's museum lot for $8. It's highly recommended you avoid the nearby $15 garage parking.
