robusta-dev When to use
Any Elasticsearch ERROR / WARN / INFO count or filter query against the
app-279-logs-* indices in this cluster.
Failed call shape (avoid)
GET app-279-logs-*/_search
{ "query": { "term": { "level": "ERROR" } } }
Returns zero hits because the field is named lvl, not level.
Working call shape
GET app-279-logs-*/_search
{ "query": { "term": { "lvl": "ERR" } } }
This index normalizes severity to the short codes ERR, WRN, INF,
DBG — full words like "ERROR" will also miss even with the right
field name.
Why this is env-specific
This team's logging library uses a custom schema with shortened field
name (lvl) and three-letter severity codes (ERR, WRN, INF,
DBG) — not documented in any public ES schema and a fresh LLM would
default to level: "ERROR".
