Monitoring processes running on a platform as a service architecture

A computer implemented method comprising:

• storing a received sample of monitored attributes of a computer process in a sample memory buffer that includes other stored samples;
• determining that the sample memory buffer is full;
• compressing the sample memory buffer;
• determining a starting position in a compressed sample file store at which to store the compressed sample memory buffer;
• storing the compressed sample memory buffer at the determined starting position in the compressed sample file store;
• storing the starting position of the stored compressed sample memory buffer at a particular location in a file position index;
• and
• storing a collection timestamp for the sample in a timestamp index at a timestamp index location that matches the particular location in the file position index.

A computer program product encoded on a non-transitory storage medium, the product comprising non-transitory, computer readable instructions for causing one or more processors to perform operations comprising:

• storing a received sample of monitored attributes of a computer process in a sample memory buffer that includes other stored samples;
• determining that the sample memory buffer is full;
• compressing the sample memory buffer;
• determining a starting position in a compressed sample file store at which to store the compressed sample memory buffer;
• storing the compressed sample memory buffer at the determined starting position in the compressed sample file store;
• storing the starting position of the stored compressed sample memory buffer at a particular location in a file position index;
• and
• storing a collection timestamp for the sample in a timestamp index at a timestamp index location that matches the particular location in the file position index.
