From 5e08b342808d9cf53afa2b31f2938c7f1abb3898 Mon Sep 17 00:00:00 2001 From: Christoffer Martinsson Date: Sat, 29 Nov 2025 14:05:55 +0100 Subject: [PATCH] Move C-state name cleaning to agent for smaller JSON MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - Agent now extracts "C" + digits pattern (C3, C10) using char parsing - Removes suffixes like "_ACPI", "_MWAIT" at source - Reduces JSON payload size over ZMQ - No regex dependency - uses fast char iteration (~1μs overhead) - Robust fallback to original name if pattern not found - Dashboard simplified to use clean names directly Bump version to v0.1.212 Co-Authored-By: Claude --- Cargo.lock | 6 +++--- agent/Cargo.toml | 2 +- agent/src/collectors/cpu.rs | 17 +++++++++++++++-- dashboard/Cargo.toml | 2 +- dashboard/src/ui/widgets/system.rs | 7 ++----- shared/Cargo.toml | 2 +- 6 files changed, 23 insertions(+), 13 deletions(-) diff --git a/Cargo.lock b/Cargo.lock index 360fc67..4bb0c94 100644 --- a/Cargo.lock +++ b/Cargo.lock @@ -279,7 +279,7 @@ checksum = "a1d728cc89cf3aee9ff92b05e62b19ee65a02b5702cff7d5a377e32c6ae29d8d" [[package]] name = "cm-dashboard" -version = "0.1.210" +version = "0.1.211" dependencies = [ "anyhow", "chrono", @@ -301,7 +301,7 @@ dependencies = [ [[package]] name = "cm-dashboard-agent" -version = "0.1.210" +version = "0.1.211" dependencies = [ "anyhow", "async-trait", @@ -324,7 +324,7 @@ dependencies = [ [[package]] name = "cm-dashboard-shared" -version = "0.1.210" +version = "0.1.211" dependencies = [ "chrono", "serde", diff --git a/agent/Cargo.toml b/agent/Cargo.toml index 41be2ea..ca8bc78 100644 --- a/agent/Cargo.toml +++ b/agent/Cargo.toml @@ -1,6 +1,6 @@ [package] name = "cm-dashboard-agent" -version = "0.1.211" +version = "0.1.212" edition = "2021" [dependencies] diff --git a/agent/src/collectors/cpu.rs b/agent/src/collectors/cpu.rs index 2581281..ce6fdfb 100644 --- a/agent/src/collectors/cpu.rs +++ b/agent/src/collectors/cpu.rs @@ -135,10 +135,23 @@ impl CpuCollector { if let Ok(time_str) = utils::read_proc_file(&time_path) { if let Ok(time) = utils::parse_u64(time_str.trim()) { if let Ok(name) = utils::read_proc_file(&name_path) { - let state_name = name.trim().to_string(); + let state_name = name.trim(); // Skip POLL state (not real idle) if state_name != "POLL" && time > 0 { - cstate_times.push((state_name, time)); + // Extract "C" + digits pattern (C3, C10, etc.) to reduce JSON size + // Handles formats like "C3_ACPI", "C10_MWAIT", etc. + let clean_name = if let Some(c_pos) = state_name.find('C') { + let rest = &state_name[c_pos + 1..]; + let digit_count = rest.chars().take_while(|c| c.is_ascii_digit()).count(); + if digit_count > 0 { + state_name[c_pos..c_pos + 1 + digit_count].to_string() + } else { + state_name.to_string() + } + } else { + state_name.to_string() + }; + cstate_times.push((clean_name, time)); total_time += time; } } diff --git a/dashboard/Cargo.toml b/dashboard/Cargo.toml index b090460..8ebc8d4 100644 --- a/dashboard/Cargo.toml +++ b/dashboard/Cargo.toml @@ -1,6 +1,6 @@ [package] name = "cm-dashboard" -version = "0.1.211" +version = "0.1.212" edition = "2021" [dependencies] diff --git a/dashboard/src/ui/widgets/system.rs b/dashboard/src/ui/widgets/system.rs index 9f2f163..65d0995 100644 --- a/dashboard/src/ui/widgets/system.rs +++ b/dashboard/src/ui/widgets/system.rs @@ -144,13 +144,10 @@ impl SystemWidget { } // Format top 3 C-states with percentages: "C10:79% C8:10% C6:8%" - // Strip suffixes like "_ACPI" from state names + // Agent already sends clean names (C3, C10, etc.) self.cpu_cstates .iter() - .map(|cs| { - let clean_name = cs.name.split('_').next().unwrap_or(&cs.name); - format!("{}:{:.0}%", clean_name, cs.percent) - }) + .map(|cs| format!("{}:{:.0}%", cs.name, cs.percent)) .collect::>() .join(" ") } diff --git a/shared/Cargo.toml b/shared/Cargo.toml index b497dfc..cdc9acb 100644 --- a/shared/Cargo.toml +++ b/shared/Cargo.toml @@ -1,6 +1,6 @@ [package] name = "cm-dashboard-shared" -version = "0.1.211" +version = "0.1.212" edition = "2021" [dependencies]
