When you have a wildcard domain ingress, then there will be no metrics for that ingress (to prevent the metrics from exploding in cardinality). To get metrics in this case you need to run the ingress controller with <code>--metrics-per-host=false</code> (you will lose labeling by hostname, but still have labeling by ingress).</p></article></div></div></main><footerclass=md-footer><divclass=md-footer-nav><navclass="md-footer-nav__inner md-grid"aria-label=Footer><ahref=../miscellaneous/class="md-footer-nav__link md-footer-nav__link--prev"rel=prev><divclass="md-footer-nav__button md-icon"><svgxmlns=http://www.w3.org/2000/svgviewbox="0 0 24 24"><pathd="M20 11v2H8l5.5 5.5-1.42 1.42L4.16 12l7.92-7.92L13.5 5.5 8 11h12z"/></svg></div><divclass=md-footer-nav__title><divclass=md-ellipsis><spanclass=md-footer-nav__direction> Previous </span> Miscellaneous </div></div></a><ahref=../multiple-ingress/class="md-footer-nav__link md-footer-nav__link--next"rel=next><divclass=md-footer-nav__title><divclass=md-ellipsis><spanclass=md-footer-nav__direction> Next </span> Multiple Ingress controllers </div></div><divclass="md-footer-nav__button md-icon"><svgxmlns=http://www.w3.org/2000/svgviewbox="0 0 24 24"><pathd="M4 11v2h12l-5.5 5.5 1.42 1.42L19.84 12l-7.92-7.92L10.5 5.5 16 11H4z"/></svg></div></a></nav></div><divclass="md-footer-meta md-typeset"><divclass="md-footer-meta__inner md-grid"><divclass=md-footer-copyright> Made with <ahref=https://squidfunk.github.io/mkdocs-material/target=_blankrel=noopener> Material for MkDocs </a></div></div></div></footer></div><scriptsrc=../../assets/javascripts/vendor.93c04032.min.js></script><scriptsrc=../../assets/javascripts/bundle.83e5331e.min.js></script><scriptid=__langtype=application/json>{"clipboard.copy":"Copy to clipboard","clipboard.copied":"Copied to clipboard","search.config.lang":"en","search.config.pipeline":"trimmer, stopWordFilter","search.config.separator":"[\\s\\-]+","search.placeholder":"Search","search.result.placeholder":"Type to start searching","search.result.none":"No matching documents","search.result.one":"1 matching document","search.result.other":"# matching documents","search.result.more.one":"1 more on this page","search.result.more.other":"# more on this page","search.result.term.missing":"Missing"}</script><script>
