I have seen the following metric tags that can impact how the metic history is kept and presented,
1. im.metric-type="ts", this keeps the metric history
2. live-config="true" and im.metric-type !="ts", only the most recent metric is kept and presented as device config; live-config="true" and im.metric-type ="ts", in additin to above, metric history is kept.
3. im.metric-type="runtime", any idea?
