Full Changelog: v0.5.0...v0.6.0-test1

v0.5.0

Added

PostgreSQL

• stat_ssl collector - per-backend SSL/TLS state
• stat_replication_slots collector - replication slot spill counters (PG14+)

Per-database

• sequences collector - sequences with last/min/max values (PG10+)
• bloat collector - heuristic table bloat estimate from pg_stats
• pgstattuple collector - authoritative bloat via pgstattuple_approx(); opt-in with -include pgstattuple

CLI

• -exclude name1,name2 flag - skip named tasks
• -include name1,name2 flag - enable default-disabled tasks

Changed

• databases collector adds datfrozenxid, datminmxid, datconnlimit, datistemplate, datallowconn
• tables collector rebuilt on pg_class + pg_stat_all_tables; adds dead-tup counters, vacuum/analyze timestamps + ages, reloptions, relpersistence, relpages, heap/table/toast sizes; capped at top 1000 by size
• indexes collector rebuilt on pg_index + pg_stat_all_indexes; adds semantic-key columns, indisvalid, idx_scan/idx_tup_read/idx_tup_fetch, relpages, index_size; capped at top 1000 by size
• running_activity_maxage collector adds max_lock_wait_age
• available_extensions collector now sourced from pg_available_extension_versions (one row per version with trust/requires/schema metadata)
• Archive root now contains radar.out with the radar binary's version (build-time stamp) and commit

Fixed

• read_ahead collector ignored virtio/xen block devices and produced unlabeled output
• hostname.out reported resolver-canonical FQDN instead of kernel hostname; added hostname_fqdn.out for the FQDN
• pg_table_size/pg_relation_size called for every relation pre-sort caused fstat overload on >1000-table clusters; now uses relpages × block_size estimate with fstat fallback for relpages = 0 rows

v0.4.1

Fixed

• Missing PostgreSQL extensions (pg_stat_statements, pg_statviz) no longer reported as errors when not installed

v0.4.0

Added

System (Linux)

• Cgroup v2 resource limit collectors (cpu.max, memory.max, memory.current, pids, cpuset, io.max, etc.)
• Cgroup v1 resource limit collectors (cpu.shares, cpu.cfs_quota, memory.limit, etc.)
• Container identity collectors (cgroup membership, mountinfo, environment, K8s namespace)
• Cloud/hardware identity collectors (DMI bios_vendor, product_name, sys_vendor, chassis_asset_tag)
• Auto-detection of container runtime (Docker, Kubernetes, containerd, LXC)

Authentication

• SSL/TLS with configurable -sslmode (prefer, disable, require, verify-ca, verify-full)
• Certificate authentication (-sslcert, -sslkey, -sslrootcert)
• GSSAPI/Kerberos authentication
• PGSSLMODE, PGSSLCERT, PGSSLKEY, PGSSLROOTCERT environment variables

Changed

• PostgreSQL driver switched from lib/pq to pgx
• Default sslmode changed from disable to prefer
• Go bumped from 1.23 to 1.24.13
• Collector errors now distinguish skip (unavailable) from real failures

Fixed

• db handle leak on ping failure
• Summary printed before zero-data check
• PGDATABASE fallback ordering with --skip-system
• Connection string quoting for values with spaces

v0.3.0

Added

System (Linux)

• clocksource collector - current kernel clocksource (tsc/hpet/kvm-clock)
• diskstats collector - raw kernel I/O counters from /proc/diskstats
• free collector - memory usage summary
• io-queue-depth collector - I/O queue depth per block device
• lscpu collector - structured CPU topology (NUMA, cores, threads, caches)
• netstat-stats collector - protocol statistics (retransmits, drops)
• numactl collector - NUMA node layout and memory
• numastat collector - per-node memory allocation statistics
• pg-service-status collector - PostgreSQL systemd service status
• resolv.conf collector - DNS resolver configuration
• ss-listeners collector - listening sockets and ports
• ss-summary collector - socket statistics summary
• timedatectl collector - NTP sync and timezone status

System (macOS)

• memory-pressure collector - system memory pressure level
• netstat-stats collector - protocol statistics
• ulimit collector - resource limits

PostgreSQL

• connection_summary collector - connection distribution by state and wait event
• database_conflicts collector - recovery conflicts from pg_stat_database_conflicts
• database_sizes collector - disk usage per database
• file_settings collector - config file parse results from pg_file_settings
• shmem_allocations collector - shared memory breakdown from pg_shmem_allocations
• stat_progress_cluster collector - CLUSTER/VACUUM FULL progress
• stat_progress_create_index collector - CREATE INDEX progress
• stat_statements_calls collector - top 100 queries by call count (pg_stat_statements)
• stat_statements_max_time collector - top 100 queries by max execution time (pg_stat_statements)
• stat_statements_total_time collector - top 100 queries by total execution time (pg_stat_statements)
• tablespace_sizes collector - tablespace disk usage
• wal_position collector - WAL position and recovery state
• wal_receiver collector - standby WAL receiver status

Testing

• Duplicate archive path detection tests for system and PostgreSQL collectors

v0.2.3

Fixed

• Deduplicate system collectors between shared and platform-specific task lists
• Prevent empty files in ZIP archive using lazy writer pattern

v0.2.2

Added

• databases_blk collector - block read/write statistics from pg_stat_database

v0.1.0

radar is an agentless, zero-dependency diagnostic data collection tool for PostgreSQL and system metrics.

Key features:

• Collects system and PostgreSQL metrics for troubleshooting
• Archives data into a timestamped ZIP file
• Handles unavailable collectors gracefully
• Zero dependencies (static binary)
