A simple way to do this would be to use embedded reports. You save your report, check the box to embed, and then take the resulting HTML and add it to your webpage. Real-time searches aren't supported, but you may want to reconsider that requirement anyways, depending on how many concurrent users you expect to have viewing these dashboards.
Report embedding lets you bring the results of your reports to large numbers of report stakeholders. With report embedding, you can embed scheduled reports in external (non-Splunk) websites, dashboards, and portals. Embedded reports can display results in the form of event views, tables, charts, maps, single values, or any other visualization type. They use the same formatting as the originating report.
