is it possible to obtain load average values (as displayed by uptime)  individually per process or user.I would like to be able to see what user is causing what load.top is not really suitable because it only displays instantaneous values.Any ideas?
Load average per process or user
statistics
Having a load average per user doesn't make much sense, since a load average only makes sense in the context of a larger system. You can, however, get usage information, which might be what you want. sa from psacct can do this, for example:Per application# sa         223730   62617.91re      31.57cp         0avio      5583k     284    1515.73re      10.45cp         0avio     46067k   perl     314      17.53re       8.90cp         0avio     65746k   redis-server*     152    1779.02re       6.46cp         0avio     56377k   vim       8    2503.01re       1.69cp         0avio      6089k   snort*   11209      99.64re       1.52cp         0avio      6100k   git   20269      33.24re       0.48cp         0avio     30273k   postgres*     140       0.48re       0.37cp         0avio      1831k   sort       3    1193.10re       0.26cp         0avio    128389k   pipe_errorlog.c       7    3146.93re       0.20cp         0avio    156983k   apache2*      26       0.16re       0.15cp         0avio     32113k   ack      19    2692.45re       0.12cp         0avio     14226k   sshd      10       0.22re       0.11cp         0avio     14464k   apt-show-versio      25       5.58re       0.08cp         0avio      7042k   apt-get     118       0.40re       0.08cp         0avio      9674k   find       4       1.51re       0.08cp         0avio      1212k   rkhunter     377       0.33re       0.07cp         0avio     14768k   rm     226    2696.40re       0.05cp         0avio     11524k   bashPer user# sa -mroot                               201825   17279.57re      13.26cp         0avio      2981k110                                   255      14.86re       7.61cp         0avio     65544knobody                                222    4659.53re       7.24cp         0avio     38149ksnort                                   1    1440.00re       1.60cp         0avio     25792k108                                   763     798.83re       1.24cp         0avio      6964k105                                 12801      31.79re       0.47cp         0avio     33102k114                                    94    2741.65re       0.09cp         0avio      9906k109                                     7   16944.24re       0.02cp         0avio     25483kDebian-exim                          3772       0.81re       0.00cp         0avio     25086kman                                   182       0.02re       0.00cp         0avio      5203k116                                    11     796.78re       0.00cp         0avio      9823k107                                    10     795.09re       0.00cp         0avio      9823kstatd                                3690       0.68re       0.00cp         0avio     25532ksshd                                   22       0.44re       0.00cp         0avio     12690kwww-data                                3       0.00re       0.00cp         0avio     11603k111                                     2   17112.17re       0.00cp         0avio     19048kmail                                    1       0.00re       0.00cp         0avio     11184k
