# # temperature.py # # Find current temperature of various system components (CPU, motherboard, # hard drives, ambient). Detection of motherboard-based temperatures (CPU # etc) uses the pysensors library, and produces a similar output to # lmsensors. HDD temperatures are obtained from the hddtemp daemon # (http://www.guzu.net/linux/hddtemp.php) which was orphaned since 2007. For # hddtemp to work, it must be started in daemon mode, either manually or with # a unit file. Manually, it would be started like this: # # sudo hddtemp -d /dev/sda /dev/sdb ... /dev/sdX # import re import sensors import socket, sys from telnetlib import Telnet from typing import List, Dict, NamedTuple from ..formatting import * from ..util import readlog, resolve from ..config import * import logging logger = logging.getLogger(__name__) class Drive(NamedTuple): path: str model: str temperature: int units: str class HddtempClient: def __init__(self, host: str='127.0.0.1', port: int=7634, timeout: int=10, sep: str='|') -> None: self.host = host self.port = port self.timeout = timeout self.sep = sep def _parse_drive(self, drive: str) -> Drive: try: drive_data = drive.split(self.sep) return Drive(drive_data[0], drive_data[1], int(drive_data[2]), drive_data[3]) except Exception as e: logger.warning("Error processing drive: {0}".format(str(drive_data))) return None def _parse(self, data: str) -> List[Drive]: line = data.lstrip(self.sep).rstrip(self.sep) # Remove first/last drives = line.split(self.sep * 2) parsed_drives = [] for drive in drives: parsed_drive = self._parse_drive(drive) if parsed_drive != None: parsed_drives.append(parsed_drive) # return [self._parse_drive(drive) for drive in drives if drive != None] # return list(filter(lambda drive: self._parse_drive(drive), drives)) return parsed_drives def get_drives(self) -> List[Drive]: # Obtain data from telnet server try: with Telnet(self.host, self.port, timeout=self.timeout) as tn: data = tn.read_all() return self._parse(data.decode('ascii')) # Return parsed data except Exception as e: logger.warning("Couldn't read data from {0}:{1} - {2}".format(self.host, self.port, str(e))) return 1 def parse_log(): logger.debug("Starting temp section") output = writetitle("temperatures") output += opentag('div', 1, 'temp', 'section') # cpu temp sensors.init() coretemps = [] pkgtemp = 0 systemp = 0 try: for chip in sensors.iter_detected_chips(): for feature in chip: if "Core" in feature.label: coretemps.append([feature.label, feature.get_value()]) logger.debug("found core " + feature.label + " at temp " + str(feature.get_value())) if "CPUTIN" in feature.label: pkgtemp = str(feature.get_value()) logger.debug("found cpu package at temperature " + pkgtemp) if "SYS" in feature.label: systemp = feature.get_value() logger.debug("found sys input " + feature.label + " at temp " + str(feature.get_value())) logger.debug("Core temp data is: " + str(coretemps)) # core_avg = reduce(lambda x, y: x[1] + y[1], coretemps) / len(coretemps) core_avg = sum(core[1] for core in coretemps) / len(coretemps) logger.debug("average cpu temp is " + str(core_avg)) coretemps.append(["avg", str(core_avg)]) coretemps.append(["pkg", pkgtemp]) coretemps = [x[0] + ": " + str(x[1]) + DEG + CEL for x in coretemps] finally: sensors.cleanup() if (systemp != 0): output += writedata("sys: " + str(systemp) + DEG) if (coretemps != ''): output += writedata("cores", coretemps) logger.info("Finished reading onboard temperatures") # drive temp # For this to work, `hddtemp` must be running in daemon mode. # Start it like this (bash): sudo hddtemp -d /dev/sda /dev/sdX... received = '' sumtemp = 0.0 data = "" fields = [] client = HddtempClient(host=config.prefs['hddtemp']['host'], port=int(config.prefs['hddtemp']['port']), sep=config.prefs['hddtemp']['separator'], timeout=int(config.prefs['hddtemp']['timeout'])) drives = client.get_drives() logger.debug("Received drive info: " + str(drives)) for drive in sorted(drives, key=lambda x: x.path): if drive.path in config.prefs['hddtemp']['drives']: sumtemp += drive.temperature fields.append(("{0} ({1})".format(drive.path, drive.model) if config.prefs['hddtemp']['show-model'] else drive.path) + ": {0}{1}{2}".format(drive.temperature, DEG, drive.units)) else: drives.remove(drive) logger.debug("Ignoring drive {0} ({1})due to config".format(drive.path, drive.model)) logger.debug("Sorted drive info: " + str(drives)) hddavg = '{0:.1f}{1}{2}'.format(sumtemp/len(drives), DEG, drives[0].units) # use units of first drive logger.debug("Sum of temperatures: {}; Number of drives: {}; => Avg disk temp is {}".format(str(sumtemp), str(len(drives)), hddavg)) fields.append("avg: " + str(hddavg)) if (config.prefs['hddtemp']['drives'] != ''): output += writedata("disks", fields) logger.info("Finished processing drive temperatures") output += closetag('div', 1) logger.info("Finished temp section") return output
