Identification
Its full user-agent string, exactly as it arrives at the gate:
SolarWinds does not publish a way to verify Pingdom's traffic. Treat its user agent as a claim, not proof: anyone can send it. Read SolarWinds's documentation.
How to block Pingdom
Add these two lines to the robots.txt file at the root of your site. Well-behaved crawlers read it before they crawl, so the change applies from Pingdom's next visit. Nothing else on your site needs to change.
# Block Pingdom from the whole site User-agent: Pingdom.com_bot Disallow: /
It only visits pages someone has asked it to watch.
Or let it visit but keep it away from part of the site:
# Let it in, but keep it out of one room User-agent: Pingdom.com_bot Allow: / Disallow: /members/

Questions site owners ask
Does Pingdom respect robots.txt?
We can't say yet. It has not fetched robots.txt here, and it has not touched a disallowed page either.
Will blocking Pingdom hurt my search rankings?
No. But links to your site will be shared without a title or preview image, which tends to get fewer clicks.
How often does Pingdom visit?
Here, about 0 requests a day over the last week. Visits to your site depend on its size, how often it changes, and how many links point to it.
