Summary | 0002664: dashboard causes high load | ||||||||
Description | when remaining on the dashboard page, load raises. the attached image shows a collectd load graph. it has been started with 1 dashboard page constantly open, load on ~ 5 after opening a second page it raised to ~ 8 after closing all dashboard pages load decresed to ~ 0 opening 1 page, load raised back to ~ 5 this happened on a mini. this most probably happens because there will be called to many cost-intensive (python vm's) tools through ajax, which means every 2? seconds. - uplinks-status.cgi could be removed completely by simply reading out a json file which should be generated by uplinksdaemon. - collectd-json.cgi could be implemented as an emi-module which also generates a json file or produces json output that should bring load back to 0 | ||||||||

both data producing scripts should be implemented as EMI status page reachable through /status/ That page should work like the commands interface calling registered methods which return json serialized python-structures. Every emi module then can register its status method |

implemented emi status json interface in /manage/status/ |

- implemented collectd status module /manage/status/status.collectd.data - replaced call to /cgi-bin/collectd-json.cgi with call to emi interface lowers load a little bit, from 4 to 3 but certainly raises emi cpu usage on the other hand; maybe we need to tune emi a little bit to do: - package collectd python interface with Collectd class - package efw-collectd emi part (setup.py) - replace uplinksdaemon status cgi with emi status interface - make dashboard.cgi use also emi status interface (?) - filter getvals in order that only needed identifiers will be fetched. creates probably a to long GET var list? |

- implemented emi status interface for uplinksdaemon and replaced in dashboard - lower ajax request resolution from 2s to 3s load is now on 2.5 |
(0004047) peter-endian (administrator) 2010-03-17 12:23 |
cache is implemented,. status values are cached for 3 seconds now, which prevents from being generated all the time and keeps load low when dashboard is opened multiple times |
(0004051) peter-endian (administrator) 2010-03-17 16:13 |
decreased initial execution time from 60s to ~10s |

wow ;) |
(0004057) peter-endian (administrator) 2010-03-17 17:43 |
load is under 2 now, nearby regardless of how many dashboards are open initial execution time is 10-15s values measured on a mini with all services enabled there is still more room to optimize, but for now it is enough. |
