Issue/Introduction

In the Experience View cards shows "No Data" instead values.

Results of the queries:

select external_id, history from (
select vertex_id, count(1) as history from appmap_vertices
where start_time > (CURRENT_DATE - INTERVAL '5 day')
group by vertex_id
order by 2 desc
limit 20) t
join appmap_id_mappings m on t.vertex_id=m.vertex_id;

• select count(*) from appmap_vertices;
• select count(*) from appmap_attribs;
• select count(*) from appmap_edges;

We have an scheduled task that runs these queries every night, in order to prevent this issue.

vacuum full analyze appmap_edges;
vacuum full analyze appmap_vertices;
vacuum full analyze appmap_attribs;

Environment

• Release: 10.7.0

Resolution

We replaced these values

# introscope.apm.data.preserving.time=365 DAYS

# introscope.apm.alert.preserving.time=62 DAYS

   with these values.

introscope.apm.data.preserving.time=90 DAYS

introscope.apm.alert.preserving.time=30 DAYS
