### Configure Grafana
### Configure Grafana
Download grafana plugin from <https://github.com/taosdata/grafanaplugin/releases/latest> .
TDengine data source plugin for Grafana is hosted on GitHub, refer to GitHub latest release page <https://github.com/taosdata/grafanaplugin/releases/latest> to download the latest plugin package. Currently it's version 3.1.3 .
It is recommended to use [`grafana-cli` command line tool](https://grafana.com/docs/grafana/latest/administration/cli/) to install the plugin.
Grafana will check the signature after 7.3 and 8.x for security. Users need additional configurations in `grafana.ini` file to allow unsigned plugins like TDengine data source.

this test case is an test case for cache error , it will let the cached data obtained by the client that has connected to taosd incorrect，
this test case is an test case for unexpectd crash for session function , it will coredump taoshell ;
root cause : table schema is changed, tag hostname size is increased through schema-less insertion. The schema cache of client taos is not refreshed.
