Frequently Asked Questions
What Traffic Patterns Should I Expect From Splunk Synthetics?
Splunk Synthetics's traffic often follows fixed intervals like a cron job. Activity may consist of short recurring checks or occasional intensive bursts, but it usually remains limited to a specific set of pages or endpoints.
Does Splunk Synthetics Follow Robots.txt Rules?
No. Splunk Synthetics is not expected to follow robots.txt rules, so a disallow rule only communicates your preference. Enforce the block with firewall or server rules, then use Agent Analytics to verify that its requests stop.
Is Splunk Synthetics Used for AI Model Training?
Not ordinarily. Splunk Synthetics is not categorized as an AI training scraper or data provider, so AI model training is not its expected purpose.
Does Blocking Splunk Synthetics Affect AI Search or Citations?
Not directly. Splunk Synthetics's expected purpose is not to supply an AI search index or retrieve pages for AI-generated answers.
Does Splunk Synthetics Access Private Content?
Only when configured with access. A team may grant Splunk Synthetics credentials to monitor staging sites or private health endpoints. Without those credentials, it sees only public pages.
How Can I Verify a Request From Splunk Synthetics?
Agent Analytics tracks Splunk Synthetics visits in real time. You can also check your server logs for requests whose user-agent string contains "Splunk Synthetics". Look for repeated checks of the same pages or endpoints at regular intervals. Because Splunk Synthetics does not publish a verification method, any client can claim its identity and a log match is only a clue.
