Domains & SEO

Domains & SEO watches the things your users reach from the internet. For each target OpsNexus records uptime and response time, reads the TLS certificate, DNS records and domain registration, and can score the page for SEO. Domains belong to the current project.

Everything uses real network requests from the OpsNexus server. Nothing is estimated.

#Add a domain

You need modify access to Domains & SEO.

1. Open Domains & SEO in the sidebar.

2. Click Add domain.

3. Fill in the form:

   Field	What to enter
   Domain or URL / Hostname	For web checks, a domain like shop.example.com or a full URL like https://example.com/health. For TCP and DNS checks, a hostname.
   Check	HTTPS, HTTP, TCP port or DNS resolution.
   Every	30 seconds, 1 minute, 5 minutes or 15 minutes.
   Port	TCP checks only. Required.
   Expected HTTP status	Web checks only. Default 200.
   Must contain (optional)	Web checks only. Text that must appear in the response body.

4. Click Add and check now. The first check runs straight away.

Each target can be added once per project.

#How checks work

Statuses:

To avoid false alarms:

• A target that fails at the network level is checked again 3 seconds later. It counts as down only if the second try fails too.
• If OpsNexus can't reach the internet at all at that moment, the check is recorded as "unknown". Unknown checks don't count for or against uptime, and the domain keeps its last real status.

Check history is kept for DOMAIN_CHECK_RETENTION_DAYS (default 30).

ALLOW_PRIVATE_TARGETS=false
DOMAIN_CHECK_RETENTION_DAYS=30

#The domain list

The tiles show how many targets are Monitored, Up, Degraded and Down, and how many have SSL expiring < 14 days.

The table shows each target's Status, Uptime 30d, Response, SSL expires, Domain expires, Hosting / CDN and SEO score. Click a target to open its detail page.

#Domain detail

The header shows the status, the last response time, when it was last checked, and the check interval. Check now runs a check and refreshes DNS, SSL and registration details. Remove stops monitoring and deletes the check history (needs full access). The domain itself is not affected.

#Uptime tab

• Availability · last 90 days: one bar per day, coloured by that day's uptime. Days below 99% stand out. Days without data are grey. The history only goes back as far as DOMAIN_CHECK_RETENTION_DAYS.
• Response time · last 24 hours: one bar per check, with failed checks marked.
• Recent failures: the time and error of each failed check in the last 24 hours.

#SSL, DNS & hosting tab

These details refresh every 6 hours, or when you click Check now.

SSL details are read for HTTPS targets only.

#Expiry alerts

SSL and registration expiry feed the alert rules SSL expiring (under 14 days) and Domain expiring (under 30 days). Uptime and response time feed Website down and Slow website. See Monitoring & alerts to change the thresholds and Notifications to choose where alerts go.

#SEO analysis

SEO analysis works for HTTP and HTTPS targets.

1. Open the domain and click the SEO tab.
2. Click Run SEO analysis (or Run analysis again).

OpsNexus fetches the page, robots.txt, the sitemap and up to 25 internal links, then scores 14 checks out of 100. A pass earns full points, a warning half, a fail none.

The report shows the SEO score, each check with its result, Recommendations sorted by impact (High, Medium, Low), and the Score history across runs.

#Core Web Vitals

To add Core Web Vitals (LCP, INP and CLS field data) to SEO reports, set a Google PageSpeed Insights API key:

PAGESPEED_API_KEY=your-key

#Traffic

The Traffic tab on a domain shows visitors and page views per day, a world map and list by country, devices, browsers, operating systems, sources, referrers and top pages. Pick Last 7 days, Last 30 days or Last 90 days.

Choose a data source the first time (needs modify access):

To use the snippet:

1. On the Traffic tab, choose Tracking snippet and click Create tracking snippet.

2. Click Copy and paste the snippet into the <head> of every page, your site template or your tag manager. It looks like this:

   html

   <script defer src="https://opsnexus.example.com/api/t/script.js" data-site="SITE_KEY"></script>

3. Visits show up within a minute.

Snippet page views are kept for TRAFFIC_RETENTION_DAYS (default 395).
