Performance of a collection of machines, arranged in a linear sequence of machines that form a linear communication orbit (LCO), is monitored. Multiple machines in the LCO receive, via the LCO, a set of rules (or various subsets of the same set of rules), each rule specifying one or a combination of conditions (e.g., a performance metric and corresponding criterion) for satisfying the rule, evaluate those rules with respect to locally occurring events and local processes, and store results of those evaluations in a local database. In response to a query sent to the machines via the LCO, each of the machines returns a report, including information identifying processes whose performance during the specified time period satisfies at least one rule in the set of one or more rules. Those reports are aggregated and used to generate a merged report reflecting performance information with respect to a set of machines.

Evaluating machine and process performance in distributed system

In a distributed system that includes a collection of machines, a server system generates a global dictionary from sampling responses received from machines in the collection of machine, at least a subject of the sampling responses including information indicating one or more terms in a corpus of information stored at a respective machine in the collection of machines. The global dictionary includes global document frequency values corresponding to the document frequencies of terms in the corpora of information stored in the collection of machines. The server system generates a similarity search query for a target document, the similarity search query including identifiers of terms in the target document and optionally document frequency information for those terms, obtained from the global dictionary, and sends, through one or more linear communication orbits, the similarity search query to one or more respective machines in the collection of machines.

System and method for generating a global dictionary and performing similarity search queries in a network

Performance of a collection of machines, arranged in a linear sequence of machines that form a linear communication orbit (LCO), is monitored. Multiple machines in the LCO receive, via the LCO, a set of rules (or various subsets of the same set of rules), each rule specifying one or a combination of conditions (e.g., a performance metric and corresponding criterion) for satisfying the rule, evaluate those rules with respect to locally occurring events and local processes, and stores results of those evaluations in a local database. In response to a performance query sent to the machines via the LCO, each of the machines returns a report, including information identifying processes whose performance during the specified time period satisfies at least one rule in the set of one or more rules. Those reports are aggregated and used to present performance information to a user.

A machine in a linear communication orbit receives a query, including a set of one or more rules, through the linear communication orbit. The machine, for each respective rule: identifies files that contain content that satisfies the respective rule, generates a first report identifying a count of files at the machine that contain content satisfying the rule, and sends the first report through the linear communication orbit to a server. The machine receives an instruction packet from an external machine that includes an instruction for establishing a direct duplex connection between the respective machine and the external machine. then sends a request to the external machine to establish the direct duplex connection. The machine sends to the external machine, via the direct duplex connection, a second report including information identifying files at the machine that contain file content satisfying each rule in the set of one or more rules.

System and method for performing search requests in a network

In a distributed system, each of N machines receives a similarity search query through a linear communication orbit. The similarity search query includes token identifiers corresponding to tokens in a target document. Each machine, in response, identifies files that meet predefined similarity criteria with respect to the target document. Subsequent to receiving the similarity search query, the machine generates a first report, including a count of files stored at the machine that meet the predefined similarity criteria with respect to the target document, and/or information identifying a set of files that meet the predefined similarity criteria with respect to the target document; and sends the first report to a server through the linear communication orbit. The server produces a merged report presenting information with respect to files at a set of machines, including the N machines, that meet the predefined similarity criteria with respect to the target document.
